Adsorption properties of chitosan for nickel ion was investigted using static adsorption method. The effects of amount of absorbent,time and temperature on nickel ion adsorption rate were investigated. The results showed that the adsorption capacity of chitosan for nickel ion in wastewater was reached to balance at 60min. The kinetics of the interactions showed better agreement with the pseudo second-order kinetics. The adsorption of nickel ion onto chitosan is exothermic,the adsorption rate increased with the increase of temperature.
