The experiment has been done for adsorption of Zn2+ on palygorskite based on purification of palygorskite clay, the result shows that the adsorption is mainly affected by such factors as vibrating rate, adsorption time, amount of adsorbent and aqueous pH, and the adsorption curve (30℃) of Zn2+ on palygorskite conforms with Langmuir equation or BET equation. In this study, the optimized technological conditions are vibrating rate 150 r/min, adsorption time 120 min, amount of adsorbent 0.120 g, and pH 6.2. The corresponding removal efficiency of Zn2+ is 95.5%.
