Abstract

A novel biosorbent, waste crab shell modified with mercaptoacetic acid (WCS-SH), was prepared and used for the removal of chromium (VI) ion from aqueous solution. The effects of adsorbent dosages and contact time on chromium (VI) removal efficiency were investigated. Experimental results indicated that the chromium (VI) removal efficiency was improved in comparison with unmodified crab shell. It was noted that the adsorption of the Cr (VI) onto WCS-SH is largely influenced by the dosage of the adsorbent and the contact time.
