Abstract:In this paper,the adsorption of cetyl trimethyl amonium bromide (CTAB) on the Sb 2O 3/H 2O interface has been studied. The adsorption isotherm is S type for CTAB and the thermodynamic calculations that based on the model of two-stages adsorption of surfactant are showed that CTAB is adsorbed on the Sb 2O 3/H 2O interface in association with two or three CTAB moleculers. The adsorption of CTAB on the Sb 2O 3/H 2O interface increases the dispersity and stability of Sb 2O 3 suspension.
Keywords:antimony powder  cetyl trimethyl amonium bromide  adsorption
