| 摘 要： | 用毛细管气相色谱法检测指甲油中5种邻苯二甲酸酯（酞酸酯）：邻苯二甲酸二甲酯（DMP）、邻苯二甲酸二乙酯（DEP）、邻苯二甲酸二丁酯（DBP）、邻苯二甲酸二（2-乙基）己酯（DEHP）、邻苯二甲酸二正辛酯（DOP）.干指甲油采用超声振荡溶解,色谱分析使用高稳定性高分离能力的溶胶-凝胶毛细管柱,采用内标法定量.在检测的6个不同商标的指甲油中有5个商标含有邻苯二甲酸酯.测定结果表明：检测限为0.16-0.50 ng;回收率为95.4%-100.4%;样品质量百分含量测定的变异系数为1.17%-2.91%.

| Abstract: | The amount of 5 phthalates in nail polishes including DMP, DEP, DBP, DEHP and DOP were measured by capillary gas chromatography. The dried nail polishes were dissolved in acetone with ultrasonication. The chromatographic analysis was carried out on a sol-gel capillary column which showed high stability and excellent separation. Inner standard method was applied in quantitative analysis. The detection limits were 0. 16-0. 50 ng. The recoveries for phthalates were 95.4%-100. 4%. The relative standard deviations for the amount of phthalates in nail polishes were 1. 17%-2.91%. |
