本文叙述了分别以钴和钇做内标,用PIXE方法分析三苯基磷羰基铑催化剂中的磷和铑。结果表明:磷和铑在催化剂中的百分含量分别为1.951％和0.113％,与理论估算值非常接近。
This paper describes the use of cobalt and yttrium as internal standards, respectively, using the PIXE method to analyze phosphorus and rhodium in triphenylphosphinocarbonyl rhodium catalysts. The results show that the percentages of phosphorus and rhodium in the catalyst are 1.951% and 0.113%, respectively, which are close to the theoretical ones.
