摘要: Fe(Ⅱ)和Ti(Ⅲ)与鲁米诺的化学发光反应已有报道,我们发现,Cr(Ⅱ)、Mo(Ⅲ)、W(Ⅲ)、U(Ⅲ)、CN-、SO32-、抗坏血酸等一大类还原剂均可与鲁米诺溶液作用产生化学发光,本文利用Jones还原柱产生V(Ⅱ),首次研究了V(Ⅱ)与鲁米诺的化学发光反应,在此基础上建立了钒的流动注射化学发光分析法,方法的检出限是8×10-11g/mL钒,线性范围是4×10-10~1×10-5g/mL钒。测定的相对标准偏差小于2%,考察了20余种常见离子对测定的干扰情况,方法已用于水样中痕量钒的测定,初步探讨了发光反应的机理。

Abstract: The chemiluminescence(CL) reaction of the V(Ⅱ)-luminol system was examined by the flow injection system with the Jones reductor. Anew method for the determination of Von the basis of this reaction is reported. The detection limit is 8 × 10-11g/mL V. The relative standard deviation is less than 2%(1.0×10-8g/mL V, n=11). The method has been applied to the determination of Vin water samples.The mechanism of V(Ⅱ)-luminol reaction is as follows:
