TL;DR: In this article, the adsorption of Remazol Brilliant Violet-5R (RBV5R) reactive dye on cocoa pod husk activated carbon (CPHAC) was investigated in batch process.
Abstract: The adsorption of Remazol Brilliant Violet-5R (RBV-5R) reactive dye on cocoa pod husk activated carbon (CPHAC) was investigated in batch process. The effects of initial dye concentration, contact time, solution temperature and pH were evaluated. The equilibrium data were fitted into Langmuir, Freundlich, Temkin and Dubinin-Radushkevich isotherm models. It was found that Freundlich model fitted the adsorption data most. The kinetic data were fitted into pseudo-first-order, pseudo-second-order, Elovich and intraparticle diffusion models. Adsorption of RBV-5R dye on CPHAC was best described by pseudo-second-order kinetic model. The adsorption of RBV-5R dye was favored at acidic pH. Thermodynamic parameters such as standard free energy ΔG0, standard enthalpy ΔH0 and standard entropy ΔS0 were calculated. The adsorption interaction of RBV-5R reactive dye on the adsorbent was found to be feasible, spontaneous and endothermic. The adsorption process followed a physisorption mechanism. © 2011 Curtin University of Technology and John Wiley & Sons, Ltd.

TL;DR: In this article, the effect of microwave heating time (0, 10, 30 and 60) on the physicochemical and functional properties of Bambara groundnut starch was investigated, and it was shown that short microwaving times (≤60) were sufficient to cause significant improvement in the pasting and thermal properties.
Abstract: Bambara groundnuts (Vigna subterranea) are a good source of starch that may be potentially used for various industrial applications. The effect of microwave heating time (0, 10, 30 and 60 s) on the physicochemical and functional properties of Bambara groundnut starch was investigated. Native and microwaved Bambara groundnut showed the A-type crystallinity pattern. However, there was a decrease in the relative crystallinity of the starch after microwaving. Microscopically, the native starch granules were smooth but had pinholes after microwaving. Microwaving resulted in significant (p ≤ 0.05) reduction in peak viscosity, hot paste viscosity, cold paste viscosity, pasting temperature and set back ratio. The swelling power of Bambara groundnut starch similarly decreased with increasing microwaving time. Microwave heating led to a shift in the gelatinization range to higher temperatures. However, the enthalpy of gelatinization decreased after microwaving. Short microwaving times (≤60 s) were sufficient to cause significant improvement in the pasting and thermal properties of Bambara groundnut starch. Microwaved Bambara groundnut starch with reduced swelling can be potentially used in food products that do not require high swelling such as noodles.

TL;DR: In this paper, the adsorption of methylene blue (MB) on the activated carbon produce from Lantana camara stem was investigated, and the results showed that MB uptake increased with the increase in pH and reached equilibrium at 60 minutes.
Abstract: This study investigated the adsorption of Methylene Blue (MB) present in wastewater onto the activated carbon produce from Lantana camara stem. The agricultural material (Lantana camara stem) was carbonized at 300°C for 2 h, ground and steam-activated. The Steam-Activated Lantana camara (SALC) stem carbon was characterized using Scanning Electron Microscope (SEM) and Fourier Transform Infrared (FTIR) Spectrophotometry before and after adsorption. Batch model experiments were conducted at 20°C to study the effects of pH, agitation time, adsorbent dosage and initial concentration of methylene blue. The equilibrium adsorption isotherms and kinetics were investigated. The FTIR bands at 3500, 2500, 2196 and 1682 cm-1 were shifted to 3646.3, 3030, 2822, 1709.05 cm-1 after MB adsorption. Similarly, the Scanning Electron Microscopy (SEM) analysis showed that the average pore size on the activated carbon was 20 μm. The Methylene Blue (MB) uptake increased with the increase in pH. Similarly, the dye adsorption increased as contact time increased, and reached equilibrium at 60 minutes. The removal of the dye increased when the dosage was increased from 0.5 - 2.0 g·L-1, at different dye concentrations (50 - 200 mg·L-1). The percentage removal decreased with increasing initial dye concentration for SALC. The adsorption isotherm data fitted well to the Freundlich isotherm (R2 = 0.989) while the experimental data fitted very well to the pseudo-second-order kinetic model (R2 = 0.99). This study suggests that adsorbent prepared from Lantana camara stem can be used effectively for the adsorption of methylene blue in wastewater.
