## Abstract The applicability of silica gels for the application in solid-phase extraction was tested. Silica was modified with ketoimine groups. Surface characteristics of the modified silica were determined by elemental analysis, NMR spectra of solid phases (29Si CP MAS NMR), analysis of pore siz

The isotherms of adsorption of CuX2 (X = Cl-, Br-, ClO-4) by silica gel chemically modified with 5-amino-1,3,4-thiadiazole-2-thiol were studied in acetone and ethanol solutions, at 25 degreesC. The following equilibria constants (in L mol-1) were determined: (a) CuCl2, 3.2 x 10(3) (ac), 2.5 x 10(3)
