Adsorption and inhibiting action of thiazole and thiodiazol derivatives

To record polarograms the solutions 2NNa2SO4 (1), 1NNH4Cl+1N NaCl(2), 3.75 N NH4Cl+0.325 N H3BO3 (3), 1N NaCl (4), 1N (NH4)2SO4 (5) and 1N NH4Cl (6) were used, which contained salts of a metal being discharged in the amount 0.05 g-ion/l. It has been established that 2-(n-aminobenzenesulphamide)-thiazol (2-ABST) does not inhibit the process of Cd2+ discharge in solutions (1), (4), (5), (6). In solution (2) the Esub(1/2) shift is not observed, but in the range of potentials - 1.1 to - 1.5 V an inconsiderable current drop at the maximum concentration (3x10-3 M) of 2-(n-aminobenzenesulphamide-)-thiazol is observed. At the same concentration in the above-mentioned range of potentials a considerable decrease in the capacity is observed
