摘　　要：采用高效液相色谱法对塑料制品中的邻苯二甲酸酯类化合物进行了测定。塑料样品经粉碎后,用乙醇溶解后超声提取,直接用高效液相色谱分析,外标法定量。该方法精密度1.07%～1.98%,回收率76.0%～96.0%。此方法简便、易行,分离度较好,可作为测定塑料制品中增塑剂邻苯二甲酸酯类的方法。A method was set up to determine the concentration of phthalates in plastics by high performance liquid chromatography （HPLC）. The comminuted plastics were extracted with ethanol, then the clear layer was separated by HPLC and detected by photo-diode-array detector. Quantitative analysis was pedonned with external standard method. A relative standard deviations was 1.07% - 1.98% and a recovery range of 76.0% -96.0% were obtained. The method is a simple, available method to detect the concentration of phthalates in plastics.
