HPLC-UV检测电子电气中多溴联苯醚的含量

目的:建立并验证了用HPLC-UV测定电子电气产品中多溴联苯醚的检测方法;方法:以甲苯为溶剂,采用索氏萃取法提取电子电气产品中10种多溴联苯醚,以相对保留时间定性,色谱峰面积定量;结果:该方法平均回收率为92.39%～100.32%,RSD为0.994%～1.377%,检测限(S/N=3)分别为1-PBDE:0.037 mg·L-1;2-PBDE:0.035 mg·L-1;3-PBDE:0.044mg·L-1;4-PBDE:0.047 mg·L-1;6-PBDE:0.045 mg·L-1;5-PBDE:0.043 mg·L-1;7-PBDE:0.036 mg·L-1;9-PBDE:0.055 mg·L-1;8-PBDE:0.054 mg·L-1;10-PBDE:0.067 mg·L-1;结论:实验表明该方法对部分电子电气产品中多溴联苯醚含量的测定符合RoHS检测的要求。

HPLC-UV Determination of PBDEs' Contents which in Electronic Products

Objective： established and tested the PBDEs which in electronic products using HPLC-UV. Methods： used toluene as solvent, adopting Soxhlet extracted the ten kinds of PBEDs from the electronic products, qualitatived with relatively retention time and quantitatived with peak area; Results： The average recovery rate was 92.39 %-100.32 %, RSD was 0.994 %-1.377 %, and the detection limit （S/N 3） respectively I-PBDE： 0.037 mg·L^-1; 2-PBDE： 0.035 mg·L^-1; 3-PBDE： 0.044 mg·L^-1; 4-PBDE： 0.047 mg·L^-1; 6-PBDE： 0.045 mg·L^-1; 5-PBDE： 0.043 mg·L^-1; 7-PBDE： 0.036 mg·L^-1; 9-PBDE： 0.055 mg·L^-1; 8-PBDE： 0.054 mg·L^-1; 10-PBDE： 0.067 mg·L^-1; Conclusion： the experiment showed that the method can meet the testing needs of the work which the RollS carry out testing of PBDEs in many electronic products.
