  The present study was designed to evaluate the interactive effects of pH, initial chromium ion concentration, biosorbent dosage and temperature of the aqueous solution on biosorption of chromium onto Syzigium cumini (java) seed powder. Based on four level Central Composite Design (CCD) involving pH from (2-6), initial chromium ion concentration from (10-30) mg/L, biosorbent dosage from (10-70) g/L and temperature of the aqueous solution from (293-313) K, a Response Surface Methodology (RSM) was standardized. The experiments designed by CCD were modeled using a polynomial equation as function of these parameters. Quadratic model proposed in the present study using CCD en suite is well suitable for analysis of experimental data. Further it was used to navigate the design space according to analysis of variance (ANOVA) results. The experimental values were on part with predicted.. View More»
