Description	The effect of the charge of adsorbed ions on their surface concentration was examined for a series of negatively charged ions at the water/1,2-dichloroethane interface.A formula has been derived relating the limiting surface concentration to the charge number z of the adsorbed ions.Application of this formula to the determination of the dissociation and equilibrium constants of surface reactions is demonstrated for slightly soluble calix[4]arene ligands.Siting of Co(II), Zn(II) and Cu(I) ions in the cationic sites of (Al)MCM-41 matrix has been investigated employing UV-Vis-NIR diffuse reflectance absorption spectroscopy and UV-Vis emission spectroscopy.Four types of cationic sites were identified in dehydrated (Al)MCM-41.Divalent cations occupy only two of these sites, while for monovalent cations are accessible four sites. Distribution of cations among sites depends on the metal loading in molecular sieve.
