A novel polystyrene chelating resin(PS-Cy) was synthesized by 1,4,7,10-tetraazacyclododecane modified chloromethylated polystyrene microsphere, and the structure of PS-Cy resin was characterized by means of Fourier transform infrared spectroscopy(FTIR).The weight gain rate and total exchange capacity of PS-Cy resin were determined, and the adsorption kinetics and isothermal adsorption process of PS-Cy resin were studied. The results show that the total exchange capacity and maximum adsorption amount to Cu2+ of PS-Cy resin reaches 5.31 mmol/g and 160.00 mg/g, respectively. The main control step of PS-Cy resin adsorption Cu2+ is governed by liquid film diffusion, and the adsorption process follows Langmuir model, which belongs to monolayer adsorption.
