摘要
Abstract
Using Agilent gas chromatography-mass spectrometry and GERSTEL ODP4 olfactory detection port,the types of odor substances in the raw water of Huayanggou Reservoir in Deyang City were analyzed,and 9 main odor substances were identified.And a detection method for 9 odor substances was established by using headspace solid-phase microextraction gas chromatography/mass spectrometry.By continuously optimizing pre-treatment parameters that affect extraction efficiency(extraction time,extraction temperature,salt precipitation concentration,etc.),the accuracy and reliability of the method were ensured.The correlation coefficients R2 of 9 substances are all greater than 0.996.The method detection limit is between 0.02-0.80 ng/L.The spiked recovery rate is 70.6％-109.9％.The relative standard deviation(SRSD)is less than 15％.This method is easy to operate and highly sensitive,and can be quickly applied to water quality acceptance and detection.关键词
