摘要
通过Ｊｏｎｅｓ还原柱产生钒（Ⅱ）、钼（Ⅲ）、铀（Ⅲ）、铁（Ⅱ）、钛（Ⅲ）、钨（Ⅲ）、铬（Ⅱ）等还原剂，利用流动注射技术研究了这些还原剂与光泽精的化学发光反应，考察了此反应用于钒、钼、铀、铁、钛、钨、铬等元素化学发光测定的可行性，并对反应机理进行了探讨．
The chemiluminescence reactions between lucigenin and V(Ⅱ),Mo(Ⅳ),U(Ⅲ),Fe(Ⅱ).W(Ⅲ ),Ti(Ⅲ),Cr(Ⅱ), which were prduced by passing V(Ⅴ),Mo(Ⅵ),U(Ⅵ),Fe(Ⅲ), W (Ⅵ), Ti (Ⅳ) and Cr (Ⅵ Ⅲ) through a small Jones reductor respectively, are investigated in detail with a flow injection system for the first time. The results show that these reactions can be used for the determination of Mo,V,U,Fe,W,Ti,Cr. The mechanism of the reaction may the that the reductants reduce dissolved oxygen to O, then O reacts with lucigenin to generate chemiluminescence.
