TL;DR: In this article, an artificial neural network (ANN) was applied for the accurate prediction of percentages of dye removal from their ternary solution by the MnO2-NP-AC adsorbent.
Abstract: MnO2 nanoparticle-loaded activated carbon (MnO2-NP-AC) as an efficient, environmental friendly and cost-effective adsorbent was synthesized and characterized using different techniques such as FE-SEM, EDX, XRD, BET and FTIR. The rapid and simultaneous ultrasound-assisted adsorption of brilliant green (BG), crystal violet (CV) and methylene blue (MB) dyes with severe spectra overlap was investigated onto MnO2-NP-AC as a novel and efficient adsorbent. The dyes in their ternary mixtures were simultaneously determined using third order derivative spectrophotometry. Response surface methodology (RSM) was successfully applied to analyze and optimize the adsorption process. The optimal conditions for pH, adsorbent dosage, initial dye concentration and sonication time were obtained to be 7.0, 0.022 g, 6 mg L−1 and 4 min, respectively. The predicted and experimental data were found to be in good agreement. An artificial neural network (ANN) was applied for the accurate prediction of percentages of dye removal from their ternary solution by the MnO2-NP-AC adsorbent. The experimental equilibrium data were modeled by applying different isotherm models. The Langmuir model was found to be the most applicable for describing the experimental equilibrium data obtained under the optimal conditions. A small amount of MnO2-NP-AC adsorbent (0.005 g) was successfully used for the removal of dyes (RE > 90.0%) in a very short time (4.0 min) with high adsorption capacity in a single component system (206.20, 234.20 and 263.16 mg g−1 for BG, CV and MB, respectively). Kinetic studies showed the applicability of the second-order kinetic model.

TL;DR: In this paper, the adsorption isotherm models such as Langmuir, Freundlich, Halsey, Temkin, Redlich-Peterson (R-P) and Sips were simulated to fit with the experimental equilibrium data.
Abstract: Peat, a natural adsorbent, has been successfully used for the removal of the hazardous water-soluble cationic dye, brilliant green (BG). Characterization of peat was carried out by determining its physical and chemical compositions such as moisture, ash, carbon%, hydrogen%, nitrogen%, and sulphur% (CHNS), crude protein and crude fat. X-ray fluorescence (XRF) was used for the determination of the percentage of elements present in peat. Functional groups present in peat were analyzed using Fourier transform infra-red (FTIR). Changes in the surface morphology of peat before and after treatment with BG were studied using Scanning Electron Microscopy (SEM). The optimization time required for establishment of an adsorption equilibrium is determined to be 2.0 h. The ambient pH of BG was used throughout the study. Adsorption isotherm models such as Langmuir, Freundlich, Halsey, Temkin, Redlich–Peterson (R–P) and Sips were simulated to fit with the experimental equilibrium data. Based on linear regression, simulated isotherm models and error analyses, the R–P isotherm fitted well for the adsorption of BG by peat. Adsorption kinetics was found to follow the pseudo second order model, with a rate constant of 0.39 g mmol−1 min−1. BG-loaded peat was successfully regenerated using 0.01 M sodium hydroxide (NaOH) solution for up to 5 consecutive cycles, while maintaining high adsorption ability of 98% even after the 5th cycle.

TL;DR: In this paper, the feasibility of Psidium guajava leaves and peels of Solanum tuberosum (Potato) as biosorbents in removal of Brilliant Green (BG) in batch mode was confirmed by UV-VIS spectroscopy.
Abstract: The aim of this study is to check the feasibility of Psidium guajava (Guava) leaves and peels of Solanum tuberosum (Potato) as biosorbents in removal of Brilliant Green (BG) in batch mode. Surface analysis of biosorbents was done by FT-IR and quantitatively analyzed by Boehm titration. The removal of dye was confirmed by UV-VIS spectroscopy. Isothermal modeling was studied by using Langmuir, Freundlich, and Temkin isotherms. Various isothermal parameters for adsorption of Brilliant Green such as mg/g, 1.173 mg/g , and −2.397 KJ/mol were noted for Solanum tuberosum peels (PP) and Psidium guajava leaves (GL), respectively. Similarly pH, moisture content, and various metals were quantitatively analyzed. Results showed that leaves of Psidium guajava were more effective for removal of Brilliant Green.

TL;DR: The reaction between the dye and ozone was first-order in nature with respect to both ozone and the dye, and the enhancement factor increased with increasing dye concentration.
Abstract: Oxidation of Brilliant Green dye was performed using ozone microbubbles in a pilot plant scale. Decolourisation was very effective at both acidic and alkaline pH. The colour of the aqueous solution was below detectable limit after 30 min at 1.7 mg/s ozone generation rate. The reaction between the dye and ozone was first-order in nature with respect to both ozone and the dye. The enhancement factor increased with increasing dye concentration. The samples were analysed by the ultra-violet–visible (UV–Vis) spectrophotometry, gas chromatography–mass spectrometry (GC–MS) and Fourier transform infra-red (FTIR) spectroscopy. From the GC–MS analysis, 13 intermediates were detected as oxidation products of this dye at various stages of oxidation. The changes in the FTIR spectra showed the destruction of the dye and the formation of new compounds. The oxidation mechanism was divided into two reaction pathways. The mineralisation of Brilliant Green was up to 80% in 60 min, as determined by total organic carbon analysis.

TL;DR: This study aimed to decolourise different dyes using two Klebsiella strains (Bz4 and Rz7) in different concentrations and incubation conditions and noticed significant effect of the process conditions.
Abstract: This study aimed to decolourise different dyes using two Klebsiella strains (Bz4 and Rz7) in different concentrations and incubation conditions. Azo (Evans blue (EB)) and triphenylmethane (brilliant green (BG)) dyes were used individually and in mixture. The toxicity of the biotransformation products was estimated. Both strains had a significant potential to decolourise the dyes in the fluorone, azo and triphenylmethane classes. The type and concentration of dye affects the decolourisation effectiveness. Differences in the dye removal potential were observed particularly in the main experiment. The best results were obtained for Bz4 in the samples with EB (up to 95.4 %) and dye mixture (up to 99 %) and for Rz7 with BG (100 %). The living and dead biomass of the strain Bz4 highly absorbs the dyes. Significant effect of the process conditions was noticed for both strains. The best results were obtained in static and semistatic samples (89–99 %) for the removal of EB and a mixture of dyes and in static samples (100 %) for BG. The decrease in zootoxicity (from class IV/V) was noticed in all samples with living biomass of the strain Bz4 (to class III/IV) and in samples with single dyes for Rz7 (to class III/IV). The decrease in phytotoxicity (from class III/IV) was noticed for Bz4 in the samples with BG and a mixture (to class III) and for Rz7 in the samples with BG (to class III). The process conditions did not affect the changes in toxicity after the process.

TL;DR: In this paper, the performance of metalloporphyrin-based catalysts in bleaching reactions of organic dyes used in the textile industry was investigated, and it was shown that the catalysts MnP-S-Mag displayed magnetic properties, which allowed their fast separation from the reaction medium with the aid of a simple magnet.
Abstract: Synthetic metalloporphyrins can oxidize organic substrates efficiently and selectively in the presence of different oxygen donors. In an attempt to propose new catalytic systems to treat industrial effluents, researchers have recently turned their attention to the performance of metalloporphyrin-based catalysts in bleaching reactions of organic dyes used in the textile industry. The present work has investigated the cationic metalloporphyrins [Mn(T4MPyP)]Ac 5 ( MnP1 ) and [Mn(Br 8 T3MPyP)]Cl 5 ( MnP2 ) immobilized on two inorganic supports, namely magnetite coated with silica obtained by the hydrolytic sol-gel process ( S-Mag ) and nanotubes of raw halloysite clay mineral ( Hallo ), as catalysts in the bleaching reaction of the dye Brilliant Green by hydrogen peroxide (30%). The catalysts elicited up to 22.9 times higher reaction rates as compared with the rates of the control reactions. It was possible to use the immobilized complexes in successive oxidation reactions without significant decrease in the catalytic activity. The catalysts MnP-S-Mag displayed magnetic properties, which allowed their fast separation from the reaction medium with the aid of a simple magnet. A 2 k full factorial design (4 factors and k levels) study of catalyst use under different experimental conditions, showed that time and molar ratio affected the dye bleaching reaction.
TL;DR: An ordered mesoporous novel material Ni-SBA-16 has been synthesized by internal pH-adjustment method as mentioned in this paper, which has shown that material possesses highly ordered mesostructure with high surface area (736m 2 /g) and large pore diameter (38nm).
TL;DR: In this paper, the removal of textile dye brilliant green (BG) from aqueous solutions by native WR and chemically activated watermelon rind (AWR) was carried out using 1:1 ortho-phosphoric acid.
Abstract: The use of low-cost and eco-friendly adsorbent such as watermelon rind (WR) has been investigated as an ideal alternate for removing dyes from wastewater. This study deals with the removal of textile dye brilliant green (BG) from aqueous solutions by native WR and chemically activated watermelon rind (AWR). Chemical activation of WR was carried out using 1:1 ortho-phosphoric acid. The loading capacity of WR and AWR was found to be 92.6 and 188.6 mg g−1, respectively. The equilibrium data were fit to Langmuir, Freundlich, and Temkin isotherms and found to have better fit to Langmuir isotherm. The sorption of BG onto WR and AWR was rapid and follows pseudo-second-order kinetic model. Thermodynamic parameters including change in free energy (∆G°), enthalpy (∆H°), and entropy (∆S°) are derived and found to be spontaneous and exothermic in nature. These observations suggest that WR can be used as a non-hazardous agro material for removal of BG from aqueous solutions.
TL;DR: The results conspicuously indicated that laccase from Peniophora sp.
Abstract: The effect of different metal ions and two redox mediators on laccase activity and laccase-catalyzed decolorization of five synthetic dyes was investigated in vitro using crude laccase from a novel white rot fungus Peniophora sp. (NFCCI-2131). The fungus effectively decolorized crystal violet and brilliant green on malt extract agar medium. Laccase activity was enhanced by metal ions such as Cd(2+), Mn(2+), Ni(2+), Co(2+), Na(+) Ca(2+), and Cu(2+). Among the different dyes tested, highest decolorization of crystal violet (96.30 %) was obtained in the presence of 1 mM ABTS followed by 86.01 % by HBT. The results conspicuously indicated that laccase from Peniophora sp. has the potential for color removal from textile dye effluent even in the presence of toxic metal ions.

TL;DR: In this article, the authors used X-ray diffraction peaks as well as vibrational features characteristic of cysteamine to detect the presence of an iron-II-rich phase with high sulfur content analogous to the iron oxide structures found in natural green rusts.
Abstract: Iron oxide nanocrystals are of great scientific and technological interest. In this work, these materials are the starting point for producing a reactive nanoparticle whose surface resembles that of natural green rusts. Treatment of iron oxide nanoparticles with cysteamine leads to the reduction of iron and the formation of a brilliant green aqueous solution of nanocrystals rich in iron(II). These materials remained crystalline with magnetic and structural features of the original iron oxide. However, new low-angle X-ray diffraction peaks as well as vibrational features characteristic of cysteamine were found in the nanocrystalline product. X-ray absorption spectroscopy (XAS), X-ray photoemission (XPS) and Mossbauer spectroscopies indicated the presence of an iron(II)-rich phase with high sulfur content analogous to the iron–oxygen structures found in natural green rusts. Electron microscopy found that these structural components remained associated with the nonreduced iron oxide cores. These sulfur-rich ...

TL;DR: In this paper, a method for the determination of formaldehyde by flow injection analysis with spectrophotometric detection is proposed, based on retarding the reaction between brilliant green and sulphite by the addition of Formaldehyde; this was investigated for formaldehyde quantification in extracts from wood-based panels.
Abstract: A method for the determination of formaldehyde by flow injection analysis with spectrophotometric detection is proposed, based on retarding the reaction between brilliant green and sulphite by the addition of formaldehyde; this was investigated for formaldehyde quantification in extracts from wood-based panels. For the first time, a heating step was explored, providing a sample throughput of 50 analyses per hour, with a limit of detection of 0.02 mg L−1 and linearity of 0.20–3.0 mg L−1, which was adequate for the expected range of formaldehyde concentration in the extracts. The mean recovery observed for actual samples was in the range of 92–106 %, with a maximum relative standard deviation of 6.0 %. The paired t-test revealed no significant difference between this method and the official Nash method, demonstrating an appropriate accuracy and precision; the method is proposed as a simple, fast and inexpensive alternative for the routine determination of formaldehyde in an aqueous medium.

Abstract: Synthesis of zeolite NaX (Zeo-NaX) from coal fly ash and its development into a photocatalyst is a rarely studied current research field. The present work focuses on this field by using cerium oxide photosensitizer over Zeo-NaX. The ceria supported zeolite-NaX (CeO2/Zeo-NaX) was prepared by introducing nanosize CeO2 into Zeo-NaX framework through ion-exchange method. The prepared catalysts were characterized by FT-IR, XRD, SEM, EDX, BET Surface area, and DRS techniques. Photocatalytic degradation of brilliant green dye (BG; 10 ppm) over the synthesized photocatalyst was studied with visible light irradiation (100 W tungsten lamp). The effects of pH, dye concentration, and catalyst dosage were also studied on the degradation reaction of BG. By varying the pH, dye concentration, and catalyst dosage of the observed percentage of photocatalytic degradation of BG are (28-100 %), (80-94 %) and (77-94 %) respectively. Thus the present work established the development of nano zeolite photocatalyst with CeO2 photosensitizer.
