价态铬的测定有多种方法。其中有的灵敏度较低,有的设备昂贵,而且一般都要预先对铬(Ⅲ)和铬(Ⅵ)进行分离富集,分析过程比较复杂。本文在前人工作基础上对水体中价态铬的液相化学发光分析法进行实验,此法依据的原理是:在碱性水溶液中,自由铬(Ⅲ)离子可以催化鲁米诺-过氧化氢体系的 Determination of valence chromium in a variety of ways. Some of them have low sensitivity and some are expensive. Generally, chromium (Ⅵ) and chromium (Ⅵ) should be separated and enriched in advance, and the analysis process is complicated. In this paper, based on the previous work on the price of chromium in the liquid state chemiluminescence assay, this method is based on the principle that: In alkaline aqueous solution, free chromium (III) ions can catalyze luminol - peroxidation Hydrogen system
