摘 要：For a better understanding the adsorption of rare earth elements（REEs） on minerals and its controlling factors, adsorption experiments were performed with kaolin in a matrix of various concentration of anion （Cl-, ClO4-, SO42-） in the pH 6.5. The adsorption of REEs onto the kaolin increase with increasing anion concentration, especially in the presence of SO42-, which is ascribe to the Na+ mass effect and anion complexation. furthermore, the heavy REEs are more adsorbed onto kaolin in presence of higher concentration of anion, especially for Cl-and SO42-, presumably due to the difference of anion complexation with light REE and heavy REEs.
