本文利用鲁米诺－ＫＩＯ４－Ｆｅ（１，１０—ｐｈｅｎ）３２＋配合物体系产生化学发光反应，建立了测定痕量铁的新的化学发光分析方法。该法以１，１０－ｐｈｅｎ为配位体，铁的检出限为１．６×１０－７ｇ／Ｌ，工作曲线响应浓度范围在１×１０－５－１×１０－３ｇ／Ｌ。在测定２×１０－４ｇ／Ｌ铁的相对标准偏差为３．５％。用于检测工业沉淀ＢａＳＯ４中痕量铁获得满意结果。 In this paper, chemiluminescence reaction of luminol-KIO4-Fe (1,10-phen) 32+ complexes was used to establish a new chemiluminescence method for the determination of trace iron. The method takes 1,10-phen as ligand, the detection limit of iron is 1.6 × 10-7g / L, and the response curve of working curve is in the range of 1 × 10-5-1 × 10-3g / L. The relative standard deviation for determination of 2 x 10-4 g / L iron was 3.5%. Used to detect trace amounts of iron in industrial precipitation BaSO4 satisfactory results.
