Abstract: A method for urea adsorption by chitosan-Zn(Ⅱ) complex was studied.The optimal conditions were obtained fromexperiments.The adsorption capacity of the complex for urea was 83.97mg/g under room temperatur and pH value between 6~7,while the original concentration of urea was 2.0mg/ml.The adsorption time was 3.0h.

Key words: chtiosan, zinc, complex, adsorption, urea
