摘要
建立了一种简单、快速、准确测定聚氯乙烯(PVC)塑料制品中邻苯二甲酸酯类增塑剂的方法。PVC塑料制品中7种邻苯二甲酸酯增塑剂可用超声辅助萃取有效地提取在氯仿溶剂中,然后用气相色谱-质谱联用法测定。方法的平均回收率在93.08%～104.1%之间,检出限(S/N= 3)在0.05～10.0mg·L^(-1)之间,相对标准偏差为0.5%～5.4%。
A simple, rapid and accurate method for the determination of plasticizers in polyvinyl chloride （PVC） plastics was established in this paper. Seven plasticizers of phthalates in PVC plastics were efficiently extracted in chloroform by means of ultrasonic-assisted extraction, then determined by GC-MS. Recoveries of the method were in the range of 93. 08%- 104. 1%. Values of detection limit （S/N= 3） were ranged in 0. 05- 10. 0 mg · L^-1 and values of RSD＇s （n=5） in the range of 0. 5%--5. 4%.
