摘要：

The influence of the isomers of aminobenzoic acid on the reaction Zn(II)/Zn(Hg) was studied in water-methanol mixtures. The o- and m-isomers accelerate this reaction in all investigated solutions. The standard rate constants are similar at the same degree of electrode coverage with these isomers in water and mixed solutions. p-Aminobenzoic acid inhibits the process of Zn(II)/Zn(Hg) electroreduction. The results suggest that the decisive role in the acceleration is played by the formation of the active complex inside the adsorption layer.
