摘要
基于锑(Ⅴ)与碘化钾的显色反应,建立了快速测定锌合金中锑的光度分析方法。在1.5 mol/L硫酸中,425 nm波长处测定,锑的线性范围和检出限分别为0.1￣10μg/mL和0.002μg/mL。本法用于锌合金中0.010%￣1.0%范围内Sb的测定,回收率98%～101%,相对标准偏差1.2%。
A rapid spectrophotometric method for the determination of Sb in zinc alloys was suggested,based on the color reaction of Sb（V） with KI in 1.5 mol/L H2SO4 media.The linear range and the detection limit for Sb（V） at 425 nm is 0.1-10 μg/mL and 0.002μg/mL ,respectively.The method was applied to the determination of Sb in zinc alloys in the range of 0.010%-1.0% with the recovery of 98%-101% and RSD of 1.2%.
