摘    要:采用了Jones柱在线还原钨(Ⅵ)为钨(Ⅲ),详细研究了钨(Ⅲ)与光泽精的化学发光反应,加入乳化剂OP能明显提高发光的信噪比,基于此建立了痕量钨的流动注射化学发光分析法。该法线性范围为1×10-6~1×10-2 g·L-1, 检出限为5×10-7 g·L-1 , 相对标准偏差为2.0%(5×10-5 g·L-1, n=11)。文中还探讨了反应机理。

关 键 词:流动注射分析  胶束增敏  光泽精  化学发光分析

Abstract:A new flow injection chemiluminescence method for the determination of tungsten is described. It is based on the chemiluminescence reaction of tungsten(Ⅲ)lucigenin system with Jones reductor. The chemiluminescence signal _ to _ noise ratio can be apparently improved by the addition of emulsor OP. The present method has a wide linear range of 1×10-6~1×10-2 g·L-1 for W(Ⅲ). The relative standard deviation is 2.0%(5×10-5 g·L-1 , n=11). The mechanism of this reaction was also discussed in detail.
Keywords:Flow injection analysis  Chemiluminescence analysis  Micelle sensitization  Lucigenin  Tungsten
