Adsorption Studies on the Removal of Hexavalent Chromium-Contaminated Wastewater Using Activated Carbon and Bentonite
Asian Journal of Chemistry
In this study, the adsorption potential of activated carbon and bentonite for removal of Cr(VI) ions from wastewater has been investigated. The study involves batch type experiments to investigate the effects of initial concentration, adsorbent dose, agitation speed, contact time, temperature and pH of solution on adsorption process and the evaluation of optimum conditions. The adsorption process has fit pseudo-second order kinetic models. Langmuir and Freundlich adsorption isotherm models weredoi:10.14233/ajchem.2013.13559 fatcat:fmudxhnl25bstniyadb3i3yx5m
