近年来,2.5次微分电分析法理论方面的研究虽已有报导,但尚未见采用滴汞电极为工作电极以及在分析测试中的应用。在经典的极谱测定中,同一底液的铁、锰连续测定由于常见底液中铁、锰合波而造成困难。段福森曾提出在三乙醇胺-氢氧化钠介质中(pH>12)测定铁、锰,该法铁、锰两波可以分开,但常见元素铜与锰峰形重叠,铅、铬与铁峰形重叠。为了建立一个连续测定铁、锰简便方法并探索在天然水样中应用的可能性,我们根据2.5次微分电分析法高灵敏度、高分
In recent years, 2.5 times the differential analysis of the theoretical studies have been reported, but have not seen the use of mercury drop electrodes as the working electrode and the application in the analysis and testing. In the classical polarographic determination, the same bottom solution of iron, manganese continuous determination of the common base solution of iron, manganese and cause difficulties. Duan Fusen has proposed in triethanolamine - sodium hydroxide medium (pH> 12) determination of iron, manganese, the method of iron, manganese two waves can be separated, but the common element of copper and manganese peak overlap, lead, chromium and iron peak shape overlapping. In order to establish a convenient method for the continuous determination of iron and manganese and explore the possibility of application in natural water samples, according to 2.5 times the differential electrokinetic analysis of high sensitivity, high score
