沉淀电导法测定土壤中氯离子的含量

摘要

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 multi-tudinous sample testing.%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。
