摘要
对测定聚丙烯中灰分的方法,包括重量法、X射线荧光光谱法、微波灰化法三种常见方法进行了综合性对比。通过精密度试验与准确度试验分别对X射线荧光光谱法、微波灰化法进行了考察,进而得到不同方法在测定过程中的优缺点。
The determination methods of ash content in polypropylene, including gravimetric method,X-ray fluorescence spectrometry and microwave muffle furnace method, were compared comprehensively. In addition, the X-ray fluorescence spectrometry and microwave muffle furnace methods were studied by precision test and accuracy test. Besides, the advantages and disadvantages of different methods in the determination process were analyzed.
