大气污染物中2-甲基丁四醇硫酸酯的质谱解析
Mass Spectrometry of 2-Methyltetrol-oganosulfates in Atmospheric Pollutant
摘要
Abstract
The liquid chromatography/ negative ion electrospray ionization mass spectrometry (LC/ ( - )ESI - MS) was used to analyze an aerosol sample collected from Dongping National Forest Park in Chongming influenced by anthropogenic activities. Diastereoisomeric organosulfates formed from the chemical reaction of SO2 and 2 - methyltetrols which are the major markers of isoprene secondary organic aerosol were found and separated. Taking the previous information into account,erythro - and threo - 2 - methyltetrol organosulfates were characterized based on mass spectral fragmentation.关键词
