Mitigation of Cu(II) from Aqueous Solution by Using Sandal Santalum Album Distillation Biomass

Abstract

In this study, mitigation of Cu(II) from aqueous solutions was evaluated using the sandal Santalum Album as biosorbent. The removal capacity of the Cu(II) was studied in batch experiments including such as initial metal concentration (25-400 mg/L), biosorbent dose (0.05-0.2 g), effects of contact time (0-1440 min), kinetics and pre-treatment of the biosorbent. The maximum removal of Cu(II) was obtained at the optimum pH of 5. The maximum equilibrium uptake for Cu(II) was  Ba(OH)2-SA(248.8 mg/g-1) at 400 ppm. Kinetics studies explained that, mitigation of the Cu(II) was very fast from 0 to 120 min and achieved equilibrium at 240 min. The equilibrium was well explained by Frendlich isotherm. Kinetics was well fitted to pseudo second order equation with high R2 values.
