摘要：

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.
