| 摘 要： | 介绍了一种在常温下测定聚氯乙烯（ＰＶＣ）塑料中有机锡化合物（ＯＴＣ）热稳定剂方法。该方法用超声波提取法有效地提取ＰＶＣ塑料中的ＯＴＣ，然后采用紫外（ＵＶ）分光光度法测定提取物中的ＯＴＣ。实验结果表明，该法排除了繁琐的提取步骤，其他添加剂基本无干扰，是一种比较简便、快速，准确的定性定量分析方法。

| Abstract: | S The method for determining organic tin compound (OTC)heat stabilizer in PVC is described .The OTC heat stabilizer is extracted from PVC effficiently by ultrasonic extraction, extracted OTC is determined by UV spectrophotometry. The test results show that this method gets rid of over-elaborate extractions, being afairly simple, rapid and accurate qualitative and quantitative analysis method. |
