摘　　要：本文的研究使用加热模块快速消解-分光光度法测定土壤中有机质的含量,通过设置不同的消解时间以及温度测定不同类型土壤有机质的含量。与传统的油浴-重铬酸钾滴定法相比,其具有快速比色、批量操作、硫酸消耗量低等优点。Sharp dissolution with heating module-spectrophotometric method was used to determine the content of organic matter in soil,and the organic matter content of different types of soil was determined by different settings of dissolution time as well as temperature.Compared with the traditional oil bath-potassium dichromate titration,it has the benefits of quick colorimetry,batch operation,and low consumption of sulfuric acid.
