TL;DR: In this article, an Nd doped ZnO (1-5%) photocatalyst was successfully synthesized via chemical co-precipitation method and the optical properties, nature, and morphology of the synthesized nanoparticles were analyzed by UV-Visible, XRD, and FESEM respectively.
Abstract: An Nd doped ZnO (1-5%) photocatalyst was successfully synthesized via chemical co-precipitation method. The optical property, nature, and morphology of the synthesized nanoparticles were analyzed by UV-Visible, XRD, and FESEM respectively. XRD study reveals that Nd has been effectively incorporated in the ZnO lattice in the lower level dosage; however, the crystalline nature has been distorted towards the increase in the Nd. The selected brilliant green dye was degraded photo-catalytically with the help of the synthesized nanoparticles and the study has been extended with catalyst dosage and dye concentration. The 2% Nd-doped ZnO showed a remarkable result of 98.26% degradation of brilliant green dye compared to the other 1,3,4 & 5 % Nd-doped ZnO nanoparticles which clearly indicates the optimization of depletion region corresponding to the maximum degradation. The increased content (3-5%) of Nd-doped ZnO exhibited moderate photocatalytic degradation of the dye due to the decreased crystalline nature which was further evidenced from XRD studies.

TL;DR: In this article, the toxicity of the organic dyes presents in the environment due to polluted discharge from industries is addressed with the synthesis of new quaternary mineral cupric antimony oxychloride (CAO) during the study of Cu Sb O O Cl system in absence of solvents.
Abstract: The toxicity of the organic dyes presents in the environment due to polluted discharge from industries is a real dilemma in the world. Here, the problem was addressed with the synthesis of new quaternary mineral cupric antimony oxychloride (CAO) during the study of Cu–Sb–O–Cl system in absence of solvents. The morphological analysis showed that synthesized matrix is rough and uneven with round and cylindrical shapes. The composition of nanomaterial verified the elemental composition as Cu, Sb and Cl. The XRD analysis revealed that synthesized product CAO is crystalline in nature where crystallite size was estimated in the range of 2–8 nm. The bond vibrations were studied through Fourier transforms infrared spectroscopy to confirm the symmetric and asymmetric vibrations in the matrix. The material parameters (grain size, dislocation line density, stresses and miller indices) of the synthesized material CAO were calculated using powder X-ray diffraction analysis. Thermogravimetric analysis was performed to study the decomposition behaviour and stability of the CAO. The copper ternary compound was used to mitigate the effect of organic dyes like Sunset yellow (26%), Methylene blue (23%), Brilliant green (20%), Methyl orange (14%) in the dyes polluted wastewater.

TL;DR: In this article, the ability of Nephelium mutabile (Pulasan) leaves (PL) in removing toxic brilliant green (BG) dye using the adsorption method was investigated.
Abstract: The main objective of this study is to investigate the ability of Nephelium mutabile (Pulasan) leaves (PL) in removing toxic brilliant green (BG) dye using the adsorption method. Batch experiments were conducted on the adsorption of BG dye using PL with a contact time of 3.5 h. Adsorption isotherm studies were analysed using six isotherm models, namely Langmuir, Freundlich, Temkin, Dubinin-Radushkevich (D-R), Redlich-Peterson (R-P) and Sips, and the results showed that Sips is the model that best fits the experimental data, with a maximum adsorption capacity (amax) of 130.3 mg g-1. The point of zero charge (pHPZC) of PL was found to be at pH 5.29. Regeneration studies showed that PL can be recovered and reused, especially after treatment with NaOH. This study demonstrates that PL can be considered as a reasonably good and cost-effective biosorbent for BG under our experimental conditions.

TL;DR: The haploid strain 15B-II4 of Saccharomyces cerevisiae was used to study in an acute experiment the toxic and mutagenic effects of arylmethane dyes, and it was shown that the dyes could increase the frequency of appearance of nuclear point mutations and cytoplasmic mutations of respiratory deficiency.
Abstract: The haploid strain 15B-II4 of Saccharomyces cerevisiae was used to study in an acute experiment the toxic and mutagenic effects of arylmethane dyes Victory Blue (C.I. 44040), Methyl Violet (C.I. 42535), Brilliant Green (C.I. 42040) and cancerogenic aminoazo dye Chrysoidine (C.I. 11270). High biological activity of all the dyes tested was found, based on such toxic effects as cell killing and growth inhibition. Also, it was shown that the dyes could increase the frequency of appearance of nuclear point mutations and cytoplasmic mutations of respiratory deficiency.
