烟用拉线中邻苯二甲酸酯类物质的测定

Determination of phthalate esters in tear tape for cigarette

探讨了烟用拉线中邻苯二甲酸酯类化合物(PAEs)的测定方法.以苯甲酸苄酯为内标和三氯甲烷作溶剂,采用超声溶剂萃取-气相色谱法测定烟用拉线中7种PAEs残留.该方法的检测限为5.05～59.68 mg/kg,相对标准偏差均小于5%,平均回收率为74.1%～120.3%.采用该方法测定分析了54种烟用拉线中PAEs含量,结果表明:有10个拉线样品检出含有1种PAEs,含量高于欧盟标准(总量<1 000 mg/kg)的仅有1个样品.

A method for the analysis of phthalate esters （PAEs） in the tear tape for cigarette was devel- oped. Ultrasonic solvent extraction combined with gas chromatography was used to determine PAEs in the tear tape for cigarette using benzyl benzoate as internal standard and chloroform as solvent. Limits of detec- tion of the method were 5.05 -59.68 mg/kg and the relative standard deviation values were less than 5% for all of the seven PAEs. The recovery values were between 74.1% to 120.3%. The method was applied to analyze 7 phthalate esters in fifty four kinds of tear tapes. The experimental results showed that 10 sam- ples were found to contain one PAEs, and only one sample was found to contain the total of PAEs which was higher than European standards, 1 000 mg/kg.
