摘　　要：在分析土壤中氯离子检测方法的基础上,提出一种通过计算理论电导率与实测电导率进行检测的方法—沉淀电导法。方法的加标回收率为93.40%-97.40%,相对标准偏差可达1.91%,满足一般的分析检测要求。此法操作简单,使用试剂种类少,适合批量样品测试。On the basis of detection analysis method of chloride ion in soil,a detection method by calculating the theoretical conductivity and actual conductivity measurement which called precipitation conductance method was put forward. The recovery of this method was 93. 40% - 97. 40%,and the relative sdandand deviation（ RSD） was 1. 91%,it was proved to be validated to meet the general requirements analysis. The operation of this method is simple. It need fewer drugs and is suitable for multitudinous sample testing.
