The natural zeolite powder was modified by chitosan to prepare modified zeolite powder as an adsorptive material which was used to remove nickle(Ⅱ) from micro-polluted water, and the effects of the adsorption time, the zeolite powder dosages, the initial concentration and the pH on the removal of nickel (Ⅱ) were investigated. The results show that the removal efficiency of modified zeolite powder is significantly better than the natural zeolite powder. When the nickel (Ⅱ) initial concentration is less than 0.2 mg/L, after adding 1.5 g/L modified zeolite powder for 20 min adsorption, the residual concentration can be reduced to below 0.02 mg/L which reaches sanitary standard for drinking water (GB 5749-2006). Raising the pH is favorable to the removal of nickel (Ⅱ). In addition, both of the adsorption processes of two zeolite powder are in the line with Freudlich adsorption isothermal model, and the adsorption index of modified zeolite powder is smaller, which can illustrate the stronger adsorbtion capacity.
