The acquisition and processing of current-time data in controlled-potential electrolyses

摘要: Abstract An on-line system is described for acquiring and processing data on the variation of current integral with time during a controlled-potential electrolysis stirred mercury-pool electrode. With simple systems it yields coulometric results that are comparable to best obtained in traditional ways. It should be possible effect substantial further improvement by controlling sources random error so small they have always been neglected coulometry. Current-time would not serve purpose because fluctuations charging faradaic currents at mercury pools make impossible secure desired accuracy precision.
