简介：用ＥＤＴＡ可增强Ｆｅ２＋催化鲁米诺与溶解氧的发光反应，将ＥＤＴＡ加入鲁米诺溶液中可使流动注射分析测亚铁的检出限降低约１６０倍。在流动注射分析的试样分流路中使用新型的锌镀铜微还原柱，可同时测定Ｆｅ２＋和Ｆｅ３＋。该微还原柱可至少测定３０００个试样。测定Ｆｅ２＋和Ｆｅ３＋的线性范围是１×１０９～１×１０５ｍｏｌ·Ｌ１，检出限分别为２．７×１０１０和３．５×１０１０ｍｏｌ·Ｌ１，测定试样的速率为６０ｈ１。Ｃｒ３＋和Ｃｏ２＋有干扰。测定混合物中的Ｆｅ２＋和Ｆｅ３＋获得满意结果，测试样的结果同标准的分光光度法结果一致。实验表明，ＥＤＴＡ起增强剂的作用，Ｆｅ２＋是催化剂，而溶解氧是氧化剂。对反应机理进行了讨论。
