建立一种基于高效液相色谱法(HPLC)邻苯二甲酸二丁酯(DBP)、邻苯二甲酸二(2-乙基己基)酯(DEHP)、邻苯二甲酸二戊酯(DPP)、邻苯二甲酸二乙酯(DEP)、邻苯二甲酸丁苄酯(BBP)、邻苯二甲酸二烯丙酯(DAP)进行检测分析。以C_(18)反相柱为分析柱,采用UV检测器对比了两种不同流动相的洗脱效果,最后选择乙腈-超纯水为流动相进行梯度洗脱,检测6种邻苯二甲酸酯类塑化剂在1~20 mg/L范围内有着良好的线性范围(R~2>0. 999 0)。在3个添加水平下,6种塑化剂的回收率在85. 57%~109. 90%,相对标准偏差小于5%。此方法的检出限范围为0. 179~0. 425 mg/L,该方法灵敏、方便且稳定,可用于食品中邻苯二甲酸酯类塑化剂的快速...

A comprehensive analytical method based on high performance liquid chromatography（HPLC） was developed for measurement in foods of 6 phthalates-Dibutyl phthalate,Dioctyl Phthalate,Di-N-pentyl phthalate,Diethyl phthalate,Butyl benzyl phthalate,Diallyl phthalate.The extracts were analyzed by HPLC using an InertsilC18column.The two kind of organic mobile phases which are acetonitril and the methanol were compared.The acetonitril-water gradient elusion was found to be more advantageous.Under the optimal conditions,the calibration curves showed a...
