INDIA (2) School of Studies in Chemistry Jiwaji University, GWALIOR – 474011 (M.P.) INDIA ABSTRACT: The use of surfactant-modified zeolites as sorbents to remove multiple types of contaminants from water has attracted great attention recently. Sorption of cationic surfactants onto negatively charged zeolite and clay mineral surfaces is controlled by cation exchange and hydrophobic interactions. When surfactant loading is less than the cation exchange capacity (CEC) of the substrate, the retention of surfactant is via cation exchange. Once the surfactant loading ... Διαβάστε περισσότερα
