摘要
Abstract
The concentration of analgin in ethanol-aqueous system was determined by using laser Raman and ATR-FTIR spectroscopy.Through comparing the spectrogram of the solvent and the analgin solution,the characteristic peak position of analgin was found.A linear relationship between the peak intensity and solution concentration was established.Off-line analysis and online monitoring of the concentration of analgin in the cooling crystallization process were done with Raman and ATR-FTIR spectroscopy.From the results,it was found that the signal of ATR-FTIR has a better response than Raman spectroscopy in the cooling crystallization process of analgin,so ATR-FTIR spectroscopy could be used for in situ monitor-ing of industrial production.关键词
