摘要
目的：建立并验证了用HPLC—UV测定各种PVC制品中欧盟限用6种增塑剂的方法；方法：以乙醚为溶剂，采用索氏萃取法提取PVC制品中6种限用邻苯二甲酸酯类增塑剂，以相对保留时间定性，峰面积进行定量；结果：该方法平均回收率为91．03％～101．01％，RSD为o．094％-4．17％，检测限（S／N=3）分别为BBP：0．014mg／L；DBP：0．081me／L；DEHP：0.066mg／L；DNOP：0．015mg／L；DINP：0．068mg／L；DIDP：0．92mg／L；结论：实验表明该方法对部分出口欧盟的PVC制品进行检验，可满足检测工作的需要。
Objective ： Established and tested PVC products using HPLC - UV determine in the EU limit of the method with the six kinds of plasticizer. Methods： using ether as solvent, adopting Soxhlet extracted the six kinds of restricting the use of Phthalate ester plasticizer in PVC, qualitative with relatively retention time and quantitative with peak area. Resuits： The mean recovery was 91.03% - 101.01%, RSD was 0. 094% -4. 17%, and the detection limit （S/N =3） respectively, BBP：0. 014mg/L; DBP：0. 081mg/L; DEHP：0. 066mg/L; DNOP：0. 015mg/L; DINP：0. 068mg/L; DIDP： 0. 92mg/L. Conclusion： The experiment showed that this method could meet the testing needs of the work which the EU carry out testing of some exports of the PVC products.
