摘要
目的：建立一种拉曼光谱技术快速测定石膏中二水硫酸钙含量的方法。方法：将不同产地的40批石膏样品做为训练集，以EDTA滴定法测定值为参考，利用OPUS软件建立二水硫酸钙拉曼光谱定量分析模型。结果：石膏中二水硫酸钙含量在97.93%~99.81%范围内的样品，所建立的拉曼光谱定量模型能快速准确测定。结论：本方法操作简便，快速，可以作为快速检测石膏主要成分含量的方法。
Objective：To develop a method for the rapid determination of CaSO4 .2H2 O in gypsum by Raman spectra. Methods：Totally 40 batches of gypsum from different origins were used as the training set, compared with the results by ENTA titration, and OPUS software was used to establish a quantitative analysis model of CaSO4 .2H2 O in gypsum by Raman spectra. Results：The estab-lished quantitative analysis model could provide a good prediction result rapidly when the content was between 97. 93% and 99. 81%. Conclusion：The method is accurate, fast and simple, which can be developed as an analysis method for CaSO4 .2H2 O in gypsum.
