- Abstract
In this paper, Taguchi method was applied to determine the optimum condition for Pb (II) removal from aqueous solution by spent Agaricus bisporus. An orthogonal array experiment design (L9(34) which is of four control factors (pH, t (contact time), m (sorbent mass), and C0 (initial Pb (II) concentration)) having three levels was employed. Biosorption capacity (mg metal/g biosorbent) and percent removal (%) were investigated as the quality characteristics to be optimized. In order to determine the optimum levels of the control factors precisely, range analysis and analysis of variance were performed. The optimum condition for biosorption capacity was found to be pH = 5.00, t = 5.0 h, m = 0.010 g, and C0 = 50 mg/L. And for percent removal, the optimum condition was found to be pH = 4.00, t = 4.0 h, m = 0.100 g, and C0 = 50 mg/L. Under these optimum conditions, biosorption capacity and percent removal can reach 60.76 mg/g and 80.50%, respectively.
