A high cost-effective treatment of sulphochromic waste is proposed employing a raw coconut coir asbiosorbent for Cr(VI) removal. The ideal pH and sorption kinetic, sorption capacities, and sorption sites were the studied biosorbent parameters. After testing five different isotherm models with standard solutions, Redlich?Peterson and Toth best fitted the experimental data, obtaining a theoretical Cr(VI) sorption capacity (SC) of 6.3mgg-1. Acid?base potentiometric titration indicated around of 73% of sorption sites were from phenolic compounds, probably lignin. Differences between sorption sites in the coconut coir before and after Cr adsorption identified fromFourier transform infrared spectra suggested a modification of sorption sites after sulphochromic waste treatment, indicating that the sorption mechanism involves organic matter oxidation and chromium uptake. For sulphocromic waste treatment, the SC was improved to 26.8±0.2mgg-1, and no adsorbed Cr(VI) was reduced, remaining only Cr(III) in the final solution. The adsorbed materialwas calcinated to obtain Cr2O3, with a reduction of more than 60% of the original mass. |
