摘要
采用偏最小二乘法定量测定了聚氯乙烯塑料样品中增塑剂DEHP的含量,该方法不受基体的干扰,结果可靠,简单快速,适合于流水线的质量控制。又采用了气相色谱法对同一样品进行测试,结果表明这两种方法的测试结果无显著差异。
The plasticizer DEHP contents in the samples of PVC plastics are quantitatively determined by partial least suquare method.This method is free of the interferen ce from the matrix,reliable,simple,rapid,and suitable for the quality control in line production.The content of DEHP in the same sample has also been determined by gas chromatography and the results showed that there weren't evident differe nces between the results from these two methods.
