摘要：

Cadmium(II) adsorption from aqueous sulphate medium on Lewatit TP260 cationic (di-Na+) ion exchange resin was investigated. The influence of operating variables such as aqueous pH, metal concentration, time and temperature on the equilibrium parameters was studied. Cadmium(II) adsorption on the resin can described by the Langmuir equation, whereas cadmium(II) uptake is particle diffusion controlled. The moving boundary particle diffusion model only,fits the initial metal adsorption on the resin.
