Potentialities of the Voltammetry of 2-Butyne-1,4-diol at Mechanically Renewed Solid Electrodes

Abstract

The electrochemical behavior of 2-butyne-1,4-diol was studied at solid platinum, gold, silver, cobalt, nickel, copper, and graphite electrodes. The working surfaces of the electrodes were renewed by cutting a thin 0.5-µm layer in the test solution immediately before recording every voltammogram. 2-Butyne-1,4-diol was oxidized in alkaline solutions at graphite, nickel, silver, and copper electrodes at positive potentials; the voltammograms obtained at these electrodes were suitable for analytical purposes. The dependence of the anodic current of 2-butyne-1,4-diol on its concentration was linear in the range from 0.03 to 0.3 g/L.
