Abstract: A extraction with acidic sweat, gas chromatography-mass spectrometry(GC/MS) method was developed to assay the soluble organotin compounds (tributyltin and dibutyltin) in the textiles. The standard curve, detection limits and recoveries were investigated, respectively. The results showed that the method is sensitive, accurate and suitable for the analysis of the soluble organotin compounds in the textiles.

Key words: gas chromatography-mass spectrometry, organotin, dibutyltin, tributyltin, textile
