Abstract
The influence of some hydroxyl-containing ligands (L) on the catalytic current in the system molybdenum(VI) – potassium chlorate has been investigated. It has been shown that the phenomenon of synergism in studying catalytic currents is associated with the activating action of L. The activity of a mixture of L and an oxidant significantly exceeds the sum of effects for their separate influence. The growth of catalytic current is possible if the catalyst (a metal ion M) possesses free or labile seats in the coordination area for formation of intermediate active compounds of the catalyst with the oxidant. It has been shown that the increase of the catalytic current is associated with formation of the intermediate active complex [Mo(V) L ClO–3]. The scheme of reactions occurring in solution and on an electrode has been elaborated. Found values of the formation constant, energy, and entropy of intermediate active complexes prove the high activity of such systems, improving the voltammetric determination of the metal catalyst by more than one order.
