Adsorption capacity of kaolinite for copper (II) under magnetic field

Abstract

The adsorption of Cu²⁺ on kaolinite under magnetic field was studied at 25°C. The magnetic effects were investigated by designing the variation of exposure time, magnetic flux density and the method of magnetic exposure. The results from these study show that the magnetic treatment significantly enhance the fraction of adsorption of Cu²⁺, the adsorption of Cu²⁺ by kaolinite increases with the increase of pH value from 2 to 6. Both the magnetic exposure time and the magnetic flux density promote the fraction of adsorption Cu²⁺ on kaolinite.
