摘要
本文提出了用PAR型极谱工作站测定水中锰含量的新方法。最佳底液条件为0．01mol／L酒石酸钾钠-2％乙二胺，可检出低达0．05mg／L的锰。锰在0．05～0．60mg／L的范围内，峰高与浓度有良好的线性关系。回收率为100．9％。变异系数为3．1％。实验了多种共存离子对猛的催化波的影响，表明该方法有较好的选择性。
This paper put forword a new type that deterAnntion of Mn in water byPAR type polarogradric working station. Optimum base solution is 0.01 mol/L potassiumsodium tatrate-2% Ethylenediamine, The detection limite is 0. 05 mg/L Mn. The methodshows a good linearity in the range of 0. 05-0. 60 mg/L Mn. Recovery rate is 100. 9%.RSD is 3. 1 %. through the test about many coedest ion's affection of Mn catalysis-wave, weproved this type have a good selectiving.
