  • A novel absorbent was prepared by cross-linking chitosan with formaldehyde and benzaldehyde followed by loaded with Zirconium. This chitosan-based material was employed as an absorbent to remove sulfate ion from aqueous solution, and its performance was investigated through batch experiments. The experimental results show that the optimum conditions of adsorption are as follows: adsorption time of 2 h, initial sulfate ion concentration of 500 mg/L, temperature of 35℃ and pH of 3.0. The equilibrium sorption process follows Langmuir isotherms well, and indicates a favorable adsorption towards SO42- with adsorption capacity of 78.65 mg/g. In addition, the adsorption process could be simulated by the second-order kinetic model. It is also showed that the adsorption capacity of Zr-loaded chitosan is 4.5 times more than that of non-loaded one, the absorbent has good acid resistance and can be reused.
