全自动测定仪在土壤阳离子交换量测定中的应用

The application of automatic measuring instrument in the determination of soil cation exchange capacity

本文使用全自动阳离子交换量前处理系统和测定仪来测定土壤中阳离子交换量,相较于传统的蒸馏和滴定步骤,试剂消耗量少,效率高,同时实验结果具有较高的准确度和精密度,可满足大批量土壤样品中阳离子交换量的分析要求。

The soil cation exchange capacity was determined by using a automatic pretreating instrument and a soil CEC meter.In comparison to the traditional distilation and titration method,this one has more advantages:less reagent usage,higher efficiency, and better accuracy and precision.Moreover,this methond meets the requirements for measuring soil samples in large quantities.
