摘　　要：用二氧化碳传感器对土壤中的碳酸盐含量进行测定,结果表明:本法不但操作简便,响应快速,而且检测下限低、灵敏度高、重现性好,适用于对大批量样品进行检测。与双指示剂法比较,测定结果相当接近,而且可以克服该法不易观察终点的不足。因而是一种较好的方法,可以在实际工作中推广应用。The determination of soil carbonates has been made by means of the carbon dioxide sensor. The results obtained show that the method is simple, rapid, sensitive and accurate with low detection limit and high level of recovery, with measurements highly in agreement with those by the double—indicator neutralization method, the proposed method overcomes the difficulties in ending—point observation, and thus can be employad in soil carbonate analysis.
