The kinetics of electroreduction of Cr3+ ion have been studied at a mercury electrode both in the absence and in the presence of chemisorbed toluene p-sulfonate ions. The rate of the reaction was considerably accelerated in the presence of the chemisorbed anions. Analysis of the data has shown that the reaction acceleration can be accounted for on the basis of Frumkin's theory for double layer effects suggesting that the reaction site is at the outer Helmholtz plane or close to it in the diffuse layer.

Cathodic Stripping

Four 6-R-2-thiouracils (R = H, methyl, propyl, benzyl) were examined by differential pulse cathodic stripping voltammetry on mercury electrode. The research led to a very sensitive analytical method that allows their determination on nanomolar level. The detection limit of the 6-propyl derivative is as low as 1.0 × 10-9 mol dm-3. The procedure is very simple and utilizes only most common chemical reagents (such as acetate buffer). The buffer concentration plays an important role in the preconcentration stage, due to the adsorption processes accompanying electrode reactions. The new analytical method was tested with commercial samples of various antithyroid drugs.
