Adsorption of Phosphate from Aqueous Solutions onto Surfactant Modified Iranian Zeolites

The presence of Phosphate in receiving waters can cause undesirable events. In This study we evaluated a natural Zeolite (i. e., clinoptilolite) in form of Surfactant Modified Zeolites (SMZS) using batch tests to adsorption of Phosphate from Aqueous Solutions. Direct comparison between none modified zeolite (NMZ), and SMZs was made for Phosphate removal in samples. It was concluded that adsorption capacity of the zeolites will remarkably improve toward Phosphate molecules by modification of its surface by a kind of surfactant namely exadecyltrimethylammonium-chloride (HDTMA-Br). Therefore SMZ is a suitable candidate for removal of Phosphate molecules from contaminated solutions
