摘　　要：利用气相色谱法对PVC料浆中残留VCM含量进行测定。此方法简便、快捷,并具有较好的精密度与准确度。残留VCM的回收率为95%～103%,精密度为0.2%～2.5%。该方法的建立对提高PVC产品的质量具有积极的指导意义。The residual VCM content in PVC slurry have been determined by gas chromatography, the method is simple and fast, it has better accuracy and precision. The recovery rate of residual VCM is from 95% to 103%, the precision is from 0.2% to 2.5%.The foundation of this method gives positive instruction for improving the quality of PVC products.
