Abstract
In this research, the technical feasibility of zeolite for Cr removal from contaminated wastewater was investigated using batch studies. Chemical treatment of zeolite with NaCl was also conducted to improve its adsorption capacity on Cr. The removal performances of all types of zeolite were evaluated and statistically compared. It was evident that the chemically treated zeolite showed significantly better Cr removal capabilities (3.23 mg/g) than as-received zeolite (1.79 mg/g) at 20 mg/l of Cr concentration. It was also found that the adsorption capacities of NaCl-treated zeolite at 5 and 10 mg/l of Cr concentrations were found to be 7.37 and 6.66 mg/g, respectively.
