锑用硼氧化钠溶液还原成锑化氢,通过石英砂加热管后,用原子吸收法于217.6nm 处测定。水样中的锑用氢氧化镧共沉淀法预富集。检测限为0.0018υg/ml,相对标准偏差为3.6%(锑含量为0.050υg/ml 级)讨论了干扰物质和生物样的分解方法。给出了沿岸海水中一些海藻、软体动物和鱼中测得的典型结果。 Antimony with sodium borohydride solution was reduced to stibine, heated by quartz sand tube, measured by atomic absorption at 217.6nm Department. Antimony in water sample was pre-enriched with lanthanum hydroxide co-precipitation method. The detection limit was 0.0018 υg / ml with a relative standard deviation of 3.6% (antimony content of 0.050 υg / ml grade). Interferences and decomposition methods of biological samples were discussed. The typical results measured in some seaweeds, molluscs and fish in coastal waters are given.
