Monitoring of Volatile Organic Compounds in Water by Blow and Capture Gas chromatography-mass spectrometry
Understanding the presence and concentration of volatile organic compounds(VOCs)in water bodies is essential for evaluating water quality safety,preventing pollution propagation,and identifying potential sources of hazards.This study combines VOCs maintenance projects at surface water stations and successfully establishes a purge and trap gas chromatography-mass spectrometry(GC-MS)method to monitor 54 volatile organic compounds in surface water.The results demonstrate that the method exhibits excellent linearity with correlation coefficients ranging from 0.991 to 1.000.The detection limits fall within the range of 0.09～0.38 μg/L,and the repeatability ranges from 3.4％to 12.8％.Moreover,the recovery rates are between 95.3％and 104.2％.This method is user-friendly,offers rapid response,and can simultaneously monitor 54 volatile organic compounds in surface water.This research provides a reliable method for monitoring and analyzing volatile organic compounds in surface water,offering technical support for water quality monitoring and early warning,and holds significant potential for application and dissemination.
