Na. Maiorova et al., ADSORPTION OF CR(VI) IONS ON PLATINUM-ELECTRODE FROM SULFURIC-ACID-SOLUTION, Russian journal of electrochemistry, 31(6), 1995, pp. 526-532
Electroreduction of chromium on platinum electrode from sulfuric acid
solution of potassium dichromate and the influence on this process of
dichromate adsorption is studied. Reduction of hexavalent chromium in
the region of positive potentials is shown to yield trivalent chromium
. Dichromate adsorption on platinum electrode results in its partial r
eduction, the resultant compound is of an anionic nature. The adsorpti
on behavior and kinetics of oxidation of the product formed are invest
igated.
