Optimization of process parameters for removal of Cr(VI) by Hypnum cupressiforme using response surface methodology (RSM)
Response surface methodology was applied to optimize the removal of chromium ion by Hypnum cupressiforme from an aqueous solution. Experiments were analyzed using response surface methodology (RSM). The biosorption process was investigated as a function of five independent factors, sorption time, sorption temperature, initial ion concentration, sorbent dosage, and mixing rate. The optimum conditions for the chromium biosorption were found to be 760 min, 313K, 30mg/L, 0.01 mg/100mL, 107 min-1 respectively, for sorption time, sorption temperature, initial ion concentration, sorbent dosage, and mixing rate. © by PSP.
