Polarographic study of solutions of cadmium(II) in acetylacetone

Abstract

The polarographic behaviour of Cd^II solutions in acetylacetone with NaClO₄ as a supporting electrolyte was studied using the following polarographic techniques: conventional d.c. polarography, normal, direct pulse polarography, normal reverse pulse polarography and differential-pulse polarography. The influence of various instrumental parameters was studied and the reversibility of the electrode process was evaluated. The heterogeneous rate constant, k_f, and the electrode transfer coefficient, α, were determined. The determination of these parameters by differential-pulse polarography was carried out by optimising the fit of the experimental data to the theoretical equation according to the modified simplex method.
