摘要: 对纺织品中邻苯二甲酸酯类环境激素在人工汗液中的迁移进行了研究,确定了用固相萃取浓缩富集人工汗液提取液中的邻苯二甲酸酯类化合物(PAEs)的最佳条件,并对纺织品中的PAEs在酸性汗液中的溶出量随时间、温度、振动频率的变化作了研究。结果表明,不同实验条件下DEP的溶出量皆远远大于DBP和DNOP,溶出量排序为DEP>>DBP>DNOP,而DEP、DBP和DNOP的溶出量随着时间的增长逐渐增大,开始时随时间增大明显,后期增长缓慢;DEP、DBP和DNOP的溶出量随温度升高而增大;振动频率对溶出量的影响不如时间、温度显著,总趋势是随着频率的升高溶出量增大。

Abstract: A method to determine the rate of phthalates migrating from the textile to human acidic sweat was studied.Trace amounts of phthalates in acidic sweat were determined by solid-phase extraction.The parameters affecting the extraction efficiency,such as extraction time,extraction temperature,vibrating frequency were discussed.It was found that the extracted amounts were arranged in the following order:(DEP(>>)DBP>DNOP.) And the extracted amounts of DEP,DBP,DNOP increased as the time prolonged and temperature raised.Vibrating frequency showed less impact on the extracted amounts than time and temperature,although they increased as the vibrating frequency increased.
