示波双电位滴定法测定枸橼酸乙胺嗪含量
OSCILLOBIPOTENTIOMETRIC TITRATION FOR THE DETERMINATION OF DIETHYLCARBAMAZINE CITRATE
-
摘要: 枸橼酸乙胺嗪又名海群生,是治疗血丝虫病的药物。其含量测定方法有非水滴定法、示波极谱滴定法、比色法等。本文介绍一种新的电位滴定法——示波双电位滴定法。其原理是用一大一小两个银片电极作指示电极,两电极间无任何外加电源,滴定终点时两电极间电位差(ΔE)产生的突变,可以用示波Abstract: A new technique of end point indication in oscillobipotentiometric titration on two Ag electrodes is described. A Cathoderay oscillograph was used to replace the conventional voltagemeasurine instrument. Excess amount of standard solution of Na-tetrapheny
