Аbout mechanizm of aliphatic alcohols’ influence on stripping voltammetry behavior of lead and cadmium

Abstract

The stripping voltammetry with the exchange of the solution without of the opening of the electrochemical circuit was applied to study the effect of the composition of the aqueous solutions, containing aliphatic alcohols on the height and potential of the peak current for Pb (II) and Cd (II). The effect of ethyl, n-propyl, n-butyl, and n-amyl alcohols was studied. The interference of the alcohols is increased with the increasing of the length of the hydrocarbon chain within the alcohol, which probably is caused by the adsorption of the alcohol onto the electrode surface.
