“…These findings are explained by dyes nature. Hence CV (cationic dye) is expected to be adsorbed more than CR (anionic dye) in basic pH (interaction between C=O, C−O‐H and –OH groups with CV molecule) ,. From FTIR, RS and XPS characterizations, results show that the surface of adsorbent contains several functional groups that may interact with the CV molecules in basic pH as compared to CR molecules.…”

“…For pH < 7.9, the adsorbent surface is positively charged, which leads to repulsive electrostatic interactions occurring between the CV molecules and the adsorbent positively charged functional groups, which were consistent with the results of Boehm's titration. As a result, we choose to work with the original solution pH, which gave a significant decolorization in the case of the both dyes …”

In this paper, the synthesis and characterization of porous carbon (PC) and porous carbon loaded ZnO nanoparticles (PC@ZnO) were investigated. The removal efficiency of Methylene Blue (MB) under ultrasound waves (UAA) and without ultrasound waves (SA) was studied considering the adsorbents dose, contact time, solution pH, temperature and initial dye concentration. Ultrasound irradiation have a positive effect on the removal efficiency of MB whereas ZnO nanoparticles incorporate in the surface of PC improve the regeneration efficiency of PC. PC@ZnO NPs shows high performance of MB removal using UAA, which was used for simultaneous removal of Crystal Violet (CV) and Congo Red (CR). The ultrasonic adsorption of CV/CR on PC@ZnO was found to be dependent on different parameters such as contact time, solution pH and initial dye concentration. The experimental results were found to follow the pseudo-second-order and Langmuir models. The adsorbed amount was found to be 64 mg g À 1 (for CR) and 109 mg g À 1 (for CV). Further, the effects of various parameters such as contact time, pH, initial dye concentration, and CV:CR ratio, were studied using central composite design coupled with response surface methodology. The data showed that the PC@ZnO has strong selective adsorption of CV dye in comparison to CR, and optimum conditions were found to be natural pH, 11.19 mg, (55:45%) of CV:CR ratio, 25 min and 30 mg L À 1 at adsorption temperature T = 25°C � 1. In these conditions, both dyes (CV and CR) are easily regenerated using HCl (0.1 M).

“…In addition, activated carbon prepared from agricultural waste came to be promising in the case of sugarcane bagasse, pomegranate peel, coconut shell [31][32]44,87]. Several activation process also been studied to improve the efficiency in removing dyes and pollutants in wastewater [38,52,46,[87][88]. However, most of the study referred in this review referring to lab-scale experiment.Based on literature information, only few study focus on comparing the adsorbent in removal of dye and pollutants [25].…”

Abstract. Industrial company such as textile, leather, cosmetics, paper and plastic generated wastewater containing large amount of dye colour. The removal of dye materials are importance as the presence of this kind of pollutant influence the quality of water and makes it aesthetically unpleasant. As their chemical structures are complicated, it is difficult to treat dyes with municipal waste treatment operations. Even a small quantity of dye does cause high visibility and undesirability. There have been various treatment technique reviewed for the removal of dye in wastewater. However, these treatment process has made it to another expensive treatment method. This review focus on the application of adsorbent in dye removal from textile wastewater as the most economical and effective method, adsorption has become the most preferred method to remove dye. The review provides literature information about different basis materials used to produce activated carbon like agricultural waste and industrial waste as well as the operational parameters factors in term of contact time, adsorbent dosage, pH solution and initial dye concentration that will affect the process in removing textile dye. This review approach the low cost and environmental friendly adsorbent for replacing conventional activated carbon.

The ability of calcined magnesite for Methylene Blue (MB), Direct Red 81 (DR81), Methyl Orange (MO) and Crystal Violet (CV) dye removal was evaluated in this study. The experiments were designed to test the hypothesis that alkaline earth carbonates can remove dyes from water through a combination of sorption and coagulative reactions involving Mg2+. To achieve that, several operational factors like residence time, dosage, adsorbent concentration and temperature were appraised. The batch study proved that calcined magnesite is effective in the treatment of MB, DR81, CV and MO contaminated water and moreover it performed well in terms of color removal. The adsorption equilibrium data were analysed by the Langmuir, Freundlich, Dubinin–Radushkevich and Temkin isotherm models, and the Dubinin–Radushkevich and Temkin models were found to be the most appropriate fit to MB and MO dyes respectively. The adsorption kinetics process primarily followed the Elovich and Pseudo-second order model, a possible indication that chemisorption was the rate limiting step during the dye uptake process. With the adsorption–desorption cycle repeated four times, the calcined magnesite regeneration efficiency for DR81 and MO loaded dyes remained very high. According to the results of this study, it can be concluded that calcined magnesite can be used effectively for the adsorption of MB, DR81, CV and MO from wastewater.
