The interaction of Pb and Zn with Al20 3 in aqueous solution was studied as a function of pH and metal ion concentration. Results indicated the complexation of metal ions by oxide surfaces is strongly pH dependent; the extent of adsorption is a function of pH with an abrupt change within approximately 2 pH units. The adsorption of Pb and Zn on aluminium oxide can be interpreted in terms of a sm...

the determination region of solubility of methanol with gasoline of high aromatic content was investigated experimentally at temperature of 288.2 k. a type 1 liquid-liquid phase diagram was obtained for this ternary system. these results were correlated simultaneously by the uniquac model. the values of the interaction parameters between each pair of components in the system were obtained for t...

The research on the adsorption equilibria, kinetics, and increase in process temperature of volatile organic compound (VOC) porous materials ensures safe production, thereby reducing production costs improving separation efficiency. Therefore, it is critical predicting entire based minimal or no experimental input adsorbate adsorbent. We discuss, this review, factors that affect performance VOC...

The problem of equilibrium and kinetics for adsorption] desorption of condensable ®apors in porous media is studied experimentally and theoretically. For adsorption, the ( network model for diffusion based on pore blocking theory with percolation in the ) network added by effecti®e medium approximation is further impro®ed. A new predicti®e model based on properties of the Bethe lattices is prop...
