The interaction between zeolite and phase transfer catalysts PTC (cationic surfactants) is of great interest. In this paper, study the influence of various physical and chemical parameters. On the adsorption of PTC on zeolite is compared according their efficiency on removal PTC at constant conditions. The optimum conditions are studied to removal PTC. Thermodynamic of adsorption are calculated to suggest the mechanism of adsorption. The effects of different conditions are studied to investigate degree of removal PTC. Furthermore, the effect of hydrophilic and hydrophobic of PTC on efficiency of adsorption on zeolite is discussed according to thermodynamic adsorption parameters. A dsorption isotherm is studied according Frumkin isotherm. The mechanism of adsorption suggested with respect micellization processes and adsorption at solution/air interface. Furthermore, cross sectional area of phase transfer catalyst affect on degree of its adsorption. The results confirm the effect of pH and chemical structures of PTC efficiency of adsorption by zeolite.
