摘要
首次提出了一种新的氧化还原电位滴定的终点指示器 界面伏打电化学池。其终点毫伏突跃性大,具有较高的分析准确度及精密度,适用于毫克级及微克级的高锰酸钾氧化还原电位滴定。
A new small-scale interfacial voltaic cell is shown to be satisfactory for potassium permanganate Oxidation-Reduction potentiometric titration in milligram and microgram amounts of the samples. This method has the advantages of being simple, rapid, highly sensitive with very sharp end-points. The standard error was 0.014. Recoveries were 99.0%-101.0% for sample amounts of 9.6 us- 4.8 mg.
