摘　　要：十氯酮（kepone）是一种毒性较高持久性有机污染物（POPs）。目前对于土壤中十氯酮的检测较少。采用索氏提取-硅胶氧化铝层析柱净化法,GC-MS对土壤中的十氯酮进行测定,该方法线性良好（r〉0.9996）,检测限较低（〈0.14μg.kg-1）,回收率稳定（平均值为90.1%~95.8%）。是测定土壤中十氯酮的较好方法。Kepone was a kind of POPs. However, there is not a standard method to determinate it in soil so far. We created a new method, i.e., extracted with Acetone by Soxhlet extraction method and purified using silicaaluminum oxide chromatography, then determined it with GC-MS. This method had a good linearity （r〉0.999 6）, lower detect limit （〈0.14 μtg.kg-1） and a stable recovery rate （average value was 90.1%-95.8%）. It is a suitable method to determinate kepone in soil.
