摘要: 以包装白酒的塑料材料为研究对象,采用气相色谱-氢火焰离子化检测器同时测定17种邻苯二甲酸酯类化合物的色谱保留时间(tR),结合化学计量学方法建立了邻苯二甲酸酯类化合物(PAEs)结构与其气相色谱保留时间之间的定量结构-色谱保留相关(QSRR)模型,并且将该模型应用于实际样品中PAEs的分析检测,考察模型的实际应用能力。结果表明,所建模型对邻苯二甲酸酯类化合物有较好的定性能力,塑料包装物中邻苯二甲酸酯类化合物迁移行为的研究分析提供了一种新途径。

Abstract: Some plastic materials for liquor packaging were studied. Retention time (tR) of 17 phthalic acid esters (PAEs) was determined by gas chromatography-flame ionization detector (GC-FID). A model of quantitative structure retention relationship (QSRR) was established through the chemical metrology method and further applied to PAEs qualitative analysis of actual samples. The result shows that the model demonstrated good qualitative capacity. Our work provides a new way to study the migration behavior of PAEs in liquor and plastic packaging materials.

Key words: phthalic acid esters (PAEs), liquor, plastic packaging, retention time of gas chromatography, quantitative structure retention relationship (QSRR)
