摘要：
The adsorption capability, dynamics and thermodynamic of Zn2+ by purified attapulgite was studied in this research. The influences of adsorption time, initial concentration and temperature on the adsorption of Zn2+ were discussed. With the rising of initial concentration, temperature and adsorption time, the removal rate and adsorption capacity of Zn2+ by attapulgite was increased. The adsorption isotherms attapulgite could be described both by the Langmuir model and Freundlich model.
