Abstract: By measuring the effect of inorganic salts on the adsorption on clay surface of amphoteric ion polymer with different molecular structures, this paper determines the characteristics of the molecular structures of amphoteric ion polymers, the law of their adsorption on clay surface,and the changes of their adsorption with inorganic salts.
