摘　　要：介绍在光离子化检测器的运行原理、特点的基础上,通过文献报道中PID数据的梳理,对PID示数与土壤中VOCs的含量进行了相关性分析,总结了高含水率情况下的数据规律。数据拟合结果说明干燥土壤中PID示数与GC-MS检测结果有较好的相关性,在实际应用中可以用PID示数快速方便地推断土壤中VOCs的含量。为PID在土壤以及地下水修复领域的大规模应用提供了理论基础。On the basis of operation principle and characteristics of photoionization detector, correlation analysis of PID and VOCs content in soil was introduced and the data regularity in high moisture conditions was also summarized by collecting and disposing the PID data in previous literature. Data fitting results showed that PID and GC - MS had good correlation in dry soil,in which VOCs content in soil could be indicated quickly and easily by PID results in practical applications. The current work also provided a theoretical basis for large-scale applications of PID detector in the field of soil and groundwater remediation.
