摘要

流动库仑法用于分析葡萄酒样品，以测定某些重金属、亚硫酸盐、酸度和乙醇含量。采用溶出计时电位法测定低浓度的重金属和亚硫酸盐含量。酸和乙醇含量的测定采用薄层库仑滴定法。

Flow-through electrochemistry in the analysis of wine

Flow through coulometry is used for analysis of wine samples for the determination of some heavy metals, sulphites, acidity and ethanol content. Low concentrations of heavy metals and sulphite contents are determined by making use of stripping chronopotentiometry. For the measurement of acid and ethanol content thin-layer coulometric titration is used.
