分析涂料中腰果酚的方法研究
Research on the Method of Analyzing Cashew Phenols in Coatings
摘要
Abstract
The Py GC/MS method is used to rapidly heat and decompose trace paint samples in an inert atmosphere.The numerous generated cracking products are effectively separated in the gas chromatography system,allowing characteristic cracking fragments to be accurately identified by mass spectrometry.In just 1 hour,the qualitative analysis of cashew phenols in trace paint samples can be carried out.We explored the experimental conditions for analyzing cashew phenols in coatings and determined that 450℃ is a relatively suitable cracking temperature.The total ion flow chromatogram of the paint sample analyzed under optimal conditions showed a peak of cashew phenols at 26.68 minutes,with a clear characteristic mass to charge ratio fragment.The peak response,shape,and separation between the two peaks were all good,which can be used for qualitative analysis.And standard curves were established using samples of cashew phenols with different mass ratios to further quantitatively analyze the content of cashew phenols in the coating.关键词
