Polarographic study of solutions of cadmium(II) in acetylacetone
Abstract
The polarographic behaviour of CdII 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, kf, 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.
