Summary
In 1975, Pungor et al. established a new method called Triangle Programmed Coulometric Titration, which allows to titrate flowing sample solutions. The following paper presents a new analytical procedure for the determination of sulphur dioxide based on this technique. To obtain this, sulphur dioxide was transferred across a semipermeable membrane from a gaseous phase into an aqueous acceptor phase. Then the SO2-concentration of the streaming aqueous phase was analysed bromometrically using the Triangle Programmed Coulometric Titration principle. The titration curves were followed continuously by an AC-bivoltammetric flow-through detector. Using this procedure a determination of SO2 concentrations between 400 and 2500 mg/m3 was possible.
