INTRODUCTION Voltammetry - from the discovery of polarography in 1922 by the chemist Jaroslav Heyrovsky, received the 1959 Nobel Prize in chemistry. The earlier voltammetric methods experienced a number of difficulties, but after in the 1960s and 1970s significant advances were made in all areas of voltammetry …
WebThe Nernst equation relating potential to the activities of reactants and products is … WebThe two first methods are about equally efficient, whereas the latter method is seen to be quite inaccurate. Results at long times compare very well with the Henderson equation. Using the full NPP set, junction potentials are time-dependent but not when applying the ENC, where the potential rises to the Henderson value immediately.
