在线预处理-催化化学发光分析方法及其应用研究

It attracted more and more attention for researchers to perform the analysis of volatile organic chemcials, Persistent Organic Pollutants and ozone at low amount level in complex environmental sample. The reason result from the complex of matrix and the low concentration level of analyte. The project integrated the highly effective of pre-treatment(mircoextraction/Purge and trap) and the sensitive quick speed of catalyzed chemiluminescence detection. By the online combined interface device, it will develop the application study of online pretreatment-catalyzed chemiluminescence detection hyphenated analysis method which is applied in the rapid and real time analysis of toxic and harmful substance(volatile organic chemcials, Persistent Organic Pollutants, ozone) in complex environmental sample such as atmosphere, soil and environmental water sample. The content including that the preparation and immobilization method study of absorbent material such as compound functional coating(adsorption/ catalyze), surface adsorption, monolithic column. The design and implementation of online combined interface device, the establish of the quick、real time、on line catalyzed chemiluminescence analysis method. The proposed method can be applied in the online separation enrichment and rapid determination of toxic and harmful substance such as volatile organic chemcials ,persistent Organic Pollutants, ozone in different phase sample such atmosphere, soil and water. Based on the hyphenated technique, the quick online real time analysis technology can be provided for the safety monitoring and quality control in the emissions and migration progress of toxic pollutants.
