摘要

In this study, performance of polyacrylamide grafted cellulose flocculant derived from Pandan leaves to treat reactive black 5 (RB5) dye from aqueous solution were investigated. Response surface methodology (RSM) and Box-Behnken design (BBD) of experiment were employed to identify the optimum condition for chemical oxygen demand (COD) reduction in RB5 dye. The optimization was based on three operating variables; initial dye concentration, flocculant dosage and pH. The optimum condition for COD reduction was achieved at initial dye concentration of 0.03 g/l with flocculant dosage of 0.06 g, at pH 11.72. Under this condition, the reduction of COD was achieved up to 54.24%. Linear and quadratic effects of flocculant dosage and pH are the most significant in affecting the degree of flocculation efficiency. The coefficient of determination (R~2) of 81.77% for percentage reduction of COD level confirms that the models used in predicting the degree of flocculation efficiency has a very good agreement with the experimental results.
