Quantitative In-Situ Determination Of Iron In A Soda-Lime-Silica Glass Melt With The Aid Of Square-Wave Voltammetry

Square-wave voltammetric measurements are fairly convenient to determine thermodynamic data and diffusion coefficients of polyvalent elements in glass melts. In principle, these methods allow the quantitative in-situ determination of the total concentrations of polyvalent ions. For the in-situ determination of small quantitites, however, improvements of the measuring and analysing procedures were necessary. This was achieved by approximating background currents using polynoms and describing Faradaic currents using theoretically derived equations.
