摘要： 假定静止溶出过程受氧化剂在电极表面的极限流量控制,在静止30s以上的条件下,本文推导出悬汞电极静止电位溶出分析法理论公式,理论计算与实验结果基本相符。

Abstract: Assuming that unstirring stripping prccess of the metal in the amalgam is controlled by the limited flox of the oxidant and providing that setting time is not less than 30 second, a theory of unstirring potcntiometric stripping analysis (UPSA) with hanging mercury drop elctrode(HMDE) is presented in this paper. Experimental verification is made and it was found that the experimental results arc in agreement with the theoretic conclusion, and so the theory of UPSAis successfully approached.
