摘要
依据《土壤和沉积物 挥发性有机物的测定 吹扫捕集/气相色谱-质谱法HJ 605-2011》,采用吹扫捕集作为前处理步骤,通过气相色谱质谱法检测环境土壤中65种VOCs,采用内标法定量,65种VOCs的检出限为0.2～1.7 ng/g,相对标准偏差RSD为0.04%～48.71%,加标回收率为70.5%～112.3%.符合环境土壤中VOCs的测定中HJ 605-2011、《环境监测规范》等相关技术文件的要求.
Abstract
According to the"Determination of Volatile Organic Compounds in Soil and Sediments by Purge and Trap/Gas Chromatography-Mass Spectrometry HJ 605-2011",65 VOCs in environmental soil were detected by gas chromatography-mass spectrometry as a pre-treatment step.The internal standard method was used for quantification.The detection limit of 65 VOCs was 0.2～1.7ng/g,the relative standard deviation(RSD)was 0.04%～48.71%,and the recovery rate was 70.5%～112.3%.Comply with the requirements of relevant technical documents such as HJ 605-2011 and the Environmental Monitoring Specification for the determination of VOCs in environmental soil.
