Description

Technical Field

[0001] The invention relates to the technical field of measuring devices, and in particular to a soil component determination preprocessing device. Background Art

[0002] The purpose of soil sample pretreatment is to make the morphology and concentration of the components to be tested in the soil sample meet the requirements of the determination method, and to reduce or eliminate the interference of coexisting components. The main methods for soil sample pretreatment are decomposition and extraction. The decomposition method is used for the determination of elements, and the extraction method is used for the determination of organic pollutants and unstable components. The function of the decomposition method is to destroy the mineral lattice and organic matter of the soil so that the elements to be tested enter the sample solution. Commonly used decomposition methods include: acid decomposition, alkali fusion decomposition, autoclave closed decomposition, microwave heating decomposition, etc. When determining organic pollutant components and unstable components after heating in the soil, as well as performing component morphology analysis, the extraction method is required. Commonly used extraction solvents are organic solvents, water and acid. In actual use, the closed decomposition method is more widely used and has less effect on the accuracy of the determination.

[0003] However, the existing closed decomposition method is generally to heat and decompose directly in the oven (or add some acid to react). During this process, if it is not taken out frequently for observation, it may cause excessive heating and decomposition, causing unnecessary trouble. In addition, during the heating process, the accumulation of soil makes the internal heating incomplete, increasing the heating time or incomplete decomposition, which also causes inaccurate data.
