The invention relates to the field of machinery, and particularly relates to a soil heavy metal determination pretreatment structure and method capable of directly removing impurities. A pretreatmentstructure is a uniform sampling structure. And the uniform sampling structure is any one of the following schemes that A, the uniform sampling structure includes a plate-shaped structure, the plate-shaped structure includes a plurality of thin tubes, and each thin tube is of a hollow tubular structure; and B, a cylindrical structure is included, the cylindrical structure includes the plurality ofthin tubes, and each thin tube is of a hollow tubular structure. The structure and the method have beneficial effects that a place needing to be sampled is selected; the hollow plate-shaped structurewith the plurality of thin tubes on the hollow plate-shaped structure are downwards extruded; soil at a plurality of sampling points enters the thin tubes; the hollow plate-shaped structure with the thin tubes is brought to a laboratory; the hollow plate-shaped structure is arranged above a sample box, and a solid extrusion part is extruded downwards; the soil is extruded into the sample box; anda foreign matter filtering structure carries out filtering twice to ensure that no foreign matter enters the soil.
Description
technical field [0001] The invention relates to the field of machinery, in particular to a fast soil heavy metal determination pretreatment structure and method capable of directly removing impurities. Background technique [0002] In the prior art, random sampling is used after sampling, but when performing digestion analysis, the amount of soil required is very small, so the randomness is very high, and the scientificity of the measurement results is doubtful, and it is very difficult to sample, and there are often sundries mixed in. Contents of the invention [0003] Purpose of the invention: In order to provide a better soil heavy metal determination pretreatment structure and method, the specific purpose is shown in the multiple substantial technical effects in the specific implementation part. [0004] In order to achieve the above object, the present invention takes the following technical solutions: [0005] Option One: [0006] A rapid soil heavy metal determin...
