摘　　要：用二氯甲烷索氏提取法对比多种萃取剂超声波提取法测定标准土壤样品回收率的结果,以实验得出二氯甲烷超声波提取法的样品加标回收率及相对标准偏差。结果表明,二氯甲烷超声萃取法提取土壤中的半挥发性有机物的时效性,准确性能够满足监测分析的要求。A comparison tests were performed for recoveries from standard soil using ultrasonic extraction with 4 kinds of solvents and Soxhlet extraction with methylene dichloride. The results showed recovery of spiked sample and RSD from method of uhrasonie extraction with methylene diehloride met timeliness and aeeuracy requirements of SVOCs monitoring in soil.
