电子电器产品中磷酸酯类化合物4种萃取方式的比较选择

Comparation and selection of four extraction methods for phosphate esters in electronic and electrical products

通过对定制3类不同材质电子电器产品(含9种磷酸酯类化合物(TCEP、TCPP、TDCPP、TPP、RDP、o-TCP、m-TCP、p-TCP、BDP))萃取,比较超声、微波、索氏、溶解-沉淀4种萃取方式的效果。数据表明溶解-沉淀萃取方式最优,该萃取方式操作方便、步骤缩短、成本减少,且采用高效液相色谱-质谱质谱法检测时无明显基底效应。

Comparative efficiency of four extraction ways(ultrasonic,microwave,Soxhlet,dissolution-precipitation)to nine phosphorus flame retardant(TCEP,TCPP,TDCPP,TPP,RDP,o-TCP,m-TCP,p-TCP,BDP)for three different types of electronic and electrical products,the method of dissolution-precipitation extraction was the best.The method has the advantages of convenient operation,shortening detection steps,reducing detection cost,obvious extraction effect,and,and no obvious basal effects were detected using high performance liquid chromatography-mass spectrometry.
