本文采用装有Ｊｏｎｅｓ柱的流动注射系统，研究了钒（Ⅱ）－光泽精体系的化学发光反应。在此基础上建立了痕量钒测定的新方法。方法的检出限３×１０￣（－１０）ｇ·ｍＬ￣（－１）；对于１．０×１０￣（－７）ｇ·ｍＬ￣（－１）钒标准溶液测定的相对标准偏差为２％（ｎ＝１１）；线性范围１．０×１０￣（－９）～９．０×１０￣（－５）ｇ·ｍＬ￣（－１），相关系数大于０．９９８０。该方法已用于水样中痕量钒的测定。对于反应机理，本文也进行了探讨。
In this paper, a flow injection system equipped with Jones column was used to study the chemiluminescence reaction of the vanadium (Ⅱ) -sperm system. On this basis, a new method for the determination of trace vanadium was established. The detection limit of the method was 3 × 10 ~ (-10) g · mL ~ (-1). The relative standard deviation of the determination of vanadium standard solution of 1.0 × 10 ~ (-7) g · mL ~ (-1) was The linear range was 1.0 × 10 -9 -9.0 × 10 -5 g · mL -1. The correlation coefficient was greater than 0.9980. This method has been used for the determination of trace vanadium in water samples. For the reaction mechanism, this article also discussed.
