Chemistry, Physics and Technology of Surface| Zusammenfassung: | The results of adsorption and spectral studies on the interaction of organic anions and cations with organosubstituted layered silicates are generalized; schemes of adsorption mechanisms are proposed. It is proved that the adsorption of organic anions is carried out due to formation of ionic associates with modifiers. Thus, the unknown fact is found – in case of the silicates substituted with long chain cationic surfactants, a desorption of the modifier and its secondary adsorption as a part of ionic associates to organic anions takes place. It has been found that large organic cations are physically adsorbed on the surface of cationic surfactant-substituted silicates and on the polycation-substituted ones – by ion exchange mechanism. |
