| 摘 要： | 本文用涂锆石墨管石墨原子吸收光谱法直接进样测定了样品中总锡含量，用氢化物发生－有机溶剂萃取石墨炉原子吸收光谱法测定了样品中有机锡，并通过差减法求得无机锡含量，无机锡和有机锡的测定检测限分别为２７ｐｇ和５８ｐｇ，精工为２．０４％和２．１３％，该方法可用于不同水样中有机和无机锡的测定，回收率在９０．５％－９８．５％之间。

| Abstract: | This paper proposed a method for the determination of inorganic tin and organotin species.Total tin contents can be directly detected by zirconium coated graphite furnace atomic absorption spectrometry,while the organotin was detected by hydride generation combined with solvent extraction and the difference between the total tin and organotin was inorganic tin.The detection limits were 58 pg and 27 pg for organotin and inorganic tin,respectively.The relative standard deviations of this procedure,were 2 13% and 2 04%,respectively.Several water samples were analyzed by this method.The recoveries ranging from 90 5% and 98 5% were obtained. |
