摘要：Octyltin compounds were detected from diaper covers by thin layer chromatography using 0.1% pyrocatechol violet solution as a spray reagent, and identified as tri-and di-n-octyltin (TOT and DOT, respectively) species by gas chromatography-mass spectrometric analysis after derivatization to tetrasubstituted organotins with propyl magnesium bromide. TOT and DOT were determined by flame photometric detection-gas chromatography. Amounts of octyltin compounds found in three diaper covers were 67.1, 97.6, and 140.1 μg/g of TOT (as its chloride) and 405.5, 579.8, and 819.2 μg/g of DOT (as its dichloride).
