摘要：Tributyl phosphate (TBP) in flame retardant textiles was analyzed by capillary gas chromatography using a flame photometric detector (FPD). A successfully cleaned up preparation using the difference in liquid-liqiud partition behaviour and a florisil cartrige column has been developed for the determination. The detection limit by this method was 10 pg. For the determination of TBP in textiles, TBP was extracted from samples with methanol under reflux at 70°C. For the removal of polar materials, distilled water was added to the extract, and TBP was reextracted into dichrolomethane from the methanolic phase. After evaporating the extract, the residue was dissolved in n-hexane, and applied to the florisil cartrige column. After washing nonpolar materials with n-hexane, TBP was eluted with n-hexane containing 10% methanol. After evaporating the elute, the residue was dissolved in n-hexane, and applied to the GC. The recoveries of TBP added to textiles at the amounts of 2, 20, 200, 2000 μg were 93-96% on the average. TBP was detected in 3 out of 8 brands in textiles finished as flame retardant by this proporsal method.
