Abstract

The adsorption capability, dynamics and thermodynamic of Zn 2+ by purified attapulgite was studied in this research.The influences of adsorption time, initial concentration and temperature on the adsorption of Zn 2+ were discussed.With the rising of initial concentration, temperature and adsorption time, the removal rate and adsorption capacity of Zn 2+ by attapulgite was increased.The adsorption isotherms attapulgite could be described both by the Langmuir model and Freundlich model.
