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)
