Abstract

Using the anaerobic granular sludge acted as biosorbent, this paper studied the biosorption and desorption of copper-containing wastewater. The results showed that, granular sludge adsorption rate up to 97.67% and citric acid got best desorption efficiency. The study of kinetics model and thermodynamics isotherm adsorption model showed that Pseudo-second Order kinetic model and Langmuir isothermal adsorption model could fitting the adsorption of Cu2+, which obtained high correlation coefficient, R2=0.9999 and R2=0.9934, respectively.
