Abstract
The inorganic molecular ions (UO 2+2 , CrO 2-4 ), together with the linear and nonlinear optical methods were used to study of the disperse SiO2 surface adsorption activity. Selective laser excitation of the luminescence spectra of uranyl ions adsorbed on SiO2 surface allowed investigations to be made of the adsorption properties for different active centers on the surface. The adsorption properties of the self-defects active centers have been investigated by means of the luminescent characteristics of the Chromate anions under multiphoton resonant excitation with subsequent ionization and dissociation of the CrO 2-4 anions. The second harmonic generation for a pure and modified sorbents was used to investigation of the formation and destruction dynamics of the self-defects active centers.
