摘要：

An interfacial voltaic cell was firstly described by B. Waligra et al for the potentiometric titration of alkaloids in non-conducting solution.Our group had developed an improved one for the potentiometric titration of various alkaloids and their salts as well as pharmaceutical preparations,organic acids inorganic acids and bases. It had also been used as an end-point indicator for the potentiometric redox titration, and precipimetric titration.
