摘要
研究了Ｆｅ（２＋）和邻二氮菲的最佳显色条件，讨论了化工部颁布的标准用于实际测定时产生偏差的主要原因，完善和修订了测定各种水样及部分化工原料和产品中微量总铁含量的操作条件，建立了一个方便、快速、准确的普遍使用于各种样品中微量总铁含量的分析方法。
The artical studied the best color conditions of Fe(2+)and o-phenanthroline,also analysed the main reasons that cause standards deviation during actual practice.The operation conditions for measurement of total amount of trace iron in all kinds of water samples,partial chemical raw materials and products were improved and modified.Theanalytical method established in this paper is proved to be convenient,fast and accurate.
