摘要
利用红外光谱法测定了PE、EVA塑料中光稳定剂(BASF5050)的含量。试验中采用外标法,即制备标准样品,根据浓度曲线确定工艺样品中光稳定剂的含量,结果表明标准曲线线性关系良好,相关系数达到0.998,回收试验数据表明回收率平均在100%±20%以内。此法可以用于塑料及其它聚合物中添加剂测定的中控方法。
The content of BASF 5050 additive in PE and EVA plastics are measured by IR spectrometry The results show that the standard sample curves are very good in linearity The correlation coefficient reaches 0 998 The rate of recovery falls within 100%±20% This method also can be applied to other polymer systems
