Abstract

The discharge of chromium effluent from various industries becomes a severe threat to the environment, creating a risk to human health and environmental aspects. In this study, Cr (VI) removal from aqueous solution by adsorption was investigated using commercially available CdS at different concentrations to consider an industrial-level large-scale application. Adsorption efficiency depends on a few parameters: pH, adsorbent dosage, initial concentration of Cr (VI) solution, temperature and contact time. For understanding the adsorption process, adsorption kinetics and adsorption Isotherm studies were applied to check the best fit mechanism of the adsorption process. The pseudo-second-order kinetics followed by the Langmuir adsorption isotherm model is the most fitted model for removing chromium using CdS. This study signifies another toxic compound, CdS, that can effectively convert Cr (VI) toxic to Cr (III) non-toxic state.
