Abstract: This work aims, optimization of simultaneous biosorption of Cr(III) and Cr(VI) onto Gelidilla acerosa, a marine macro algae using multiple response optimization combined with central composite design of experiments. The three important physicochemical parameters of biosorption such as initial pH, initial concentration of metal solution and biosorbent dosage were optimized. The most favorable condition for simultaneous removal of Cr(III) and Cr(VI) were: pH 2.8, initial concentration 20 mg l-1 and biosorbent dosage 0.05g with maximum overall desirability of 1.0. Surface morphological features of biosorbent were studied using FTIR.
