摘要：

Stripping potentiometry (SP) has been used effectively for the determination of trace levels of several metal species in solution. Indium ion, which can be readily reduced and has a high solubility in mercury, can be determined directly using SP. The reduction potential of indium is located between those of lead and cadmium, necessitating optimization of several experimental parameters for successful quantitative analysis. A method for the SP of In(III) is presented which utilizes constant current stripping analysis (CCSA) at a mercury-film glassy carbon electrode in KCI solutions in the presence of Pb(II) and Cd(II).
