| 摘 要： | 采用氢化物发生原子荧光光谱法测定水中痕量锑。用盐酸和5%硫脲+5%抗坏血酸混合溶液处理样品,并以1.0%硼氢化钾和0.5%氢氧化钾为还原剂,在5%的盐酸介质中测定锑,锑的检出限(DL)为:0.028μg/L,相对标准偏差RSD(n=15)为3.1%,水样的加标回收率在94.3%～103.6%之间。本方法具有操作简便、快速、基体干扰少、灵敏度高和重现性好等优点,可用于水样中锑的测定。

| Abstract: | HG-AFS was applied to the determination of trace amounts of antimony in water.The water sample was treated by HCL and 5% Thiourea（H2NSCNH2）～5% Ascorbic acid（C6H8O6）.The method is based on the reaction of antimony（Sb） with KBH4 to form the hydride gas in medium of 5% HC1.The detection limits（DL） are 0.028μg/L.and it is RSD（n=15）found was 3.1%,the recoveries of Sb obtained by standard addition method are in the ranges of 94.8%～102.3%.The method is simple,rapid,less matrix interference and high sensitivity and reproducible.It can be applied to determination of Sb in water. |
