The removal efficiency of Cr (VI) from aqueous solution onto modified calyx of gold coast bombax was studied. The effects of contact time, adsorbent dosage, solution concentration and pH of solution on adsorption of Cr (VI) were optimized using the 24 factorial design experiment. Optimum experimental adsorption was 96.53±0.03% with a predicted response of 97.75±0.19% and a residual value of -1.04 at 10 mg/dm3 solution concentration. Main and interaction effects of the four adsorption parameters revealed adsorbent dosage and the interaction of adsorbent with solution concentration had the most significant influence on the removal of Cr (VI) from solution. Correlation coefficient of the experiment and predicted values indicate a good performance of the model.
