采用Luminol-H。O。Air(巨)化学发光反应体系作为分析检测方法,建立了一个测定地质样品中痕量锑的化学发光分析法。方法的原理是用AgNO。吸收由样品发生的氢化锑气体,使吸收液中生成Sb(巨)与过量的K。Cr。O,反应生成Cr(1),方法的检出限为0.6us/mlSb,工作曲线的线性范围是2~1000ng/mlSb,测定的相对标准偏差小于5%。本方法已用于地质样品中痕量佛的测定。
Luminol-H is used. O. Air (Giant) Chemiluminescence Reaction System As an analytical method, a chemiluminescence method for the determination of trace antimony in geological samples was established. The principle of the method is to use AgNO. Absorption of antimony hydride gas generated by the sample, so that the absorption liquid generated Sb (giant) and excess K. Cr. O, the reaction produces Cr (1). The detection limit of the method is 0.6us / mlSb. The linear range of the working curve is 2 ~ 1000ng / mlSb. The relative standard deviation of the determination is less than 5%. The method has been applied to the determination of trace Buddha in geological samples.
