摘要: 电位溶出分析法近年来有迅速的发展和广泛的应用,八十年代初开始的该法理论研究的进展不仅定量解释了实验事实,而且开拓了该法应用的新领域,本文报告悬汞电极电位溶出分析法的理论研究结果。

Abstract: Equations describing the potentiometric stripping analysis (PSA) with a hanging mercury dropping electrode (HMDE) are deduced. Transition time equation and E-t curve equation are obtained and quantitative relationship between transition time and parameters, e.g., the cocentrations of determined ions and oxidant preconcentration time, electrode radium, etc, is also obtained. All the theoretic conclusions were verified experimentally, and the results are in agreement with the theory.
