铜铁试剂是早就用于分析工作的试剂之一。它常用于沉淀和萃取分离,也用于重量法和安培法测定各种元素。但是关于铜铁试剂盐的生成条件的系统内容还未在文献资料中见到。尽管很多(特别是带多电荷的)金属离子的铜铁试剂盐是能在较宽的酸度范围内形成和被萃取的,但在某些文献中,关于在狭窄的pH范围内萃取 Copper and iron reagents is one of the reagents that has long been used in analytical work. It is often used for precipitation and extraction separation, but also for gravimetric and amperometric determination of various elements. However, the system conditions for the production conditions of copper and iron reagent salts have not been found in the literature. Although many (especially multi-charged) copper ion reagents for metal ions are capable of forming and being extracted over a wide range of acidity ranges, in some of the literature on extraction of copper
