摘　　要：建立了超声波萃取、氟罗里硅土柱净化、气相色谱／质谱联用选择离子扫描模式测定土壤样品中多氯联苯Arochlor系列的方法。方法线性良好，灵敏度高，RSD为9.5％-12.2％，加标回收率为65.0％～105％，标准土壤样品的测定结果也符合要求。The method was established for determination of Arochlors in soil by ultrasonic wave extraction, Florisil column purification and selected ion GC/MS. It was good linear relationship between Arochlors concentrations and instrument responses, high sensitivity, and the recovery from 65.0% to 105% , RSD from 9.5% to 12.2%. The test result of standard reference soil sample was correct.
