Abstract
The attapulgite had so large specific-surface areas that it had a good adsorption effect for metal zinc(Ⅱ) ions.Based on the adsorption of attapulgite to zinc(Ⅱ) ions in the solution for the study of experiments,the results showed that in alkaline conditions,chemical adsorption performance was well.Adsorption characteristics and mechanisms in the adsorption thermodynamics experiments were discussed and the results showed that adsorption properties of the attapulgite to zinc(Ⅱ) ion was more accord with the Freundlich monolayer adsorption model.Unit adsorption concentration k value was increased then decreased as the temperature increased.The influence of temperature for adsorption amount n value showed a trend of decreased,which indicated the physical adsorption effect was well.
