Unmodified zeolites show little affinity for anions due to the fact that their surfaces are negatively charged. However modification of zeolites with amines turns their negative surface charge to positive and creating higher adsorption capacity for anions. In this study, polyaniline-clinoptilolite composite was prepared by polymerization of anilinium on the surface of zeolite. The composite...
