Description

Detection device for metal content of soil Technical Field The utility model relates to the technical field of soil metal content detection, in particular to a device for detecting soil metal content. Background Soil is an important constituent of natural environment and is also a basic resource for agricultural production. However, with the acceleration of the urban and industrial processes, heavy metal elements enter the soil in large quantities through the approaches of sewage irrigation, atmospheric smoke sedimentation, industrial waste discharge and the like. These heavy metals cannot be decomposed by soil microorganisms and are easy to accumulate, thereby causing heavy metal pollution of the soil. Heavy metal elements in the soil can be absorbed by plants and enriched in animals to enter a food chain, so that the quality safety of agricultural products and public health are endangered. For example, heavy metals such as lead, cadmium, mercury, etc. accumulate in the human body, leading to various health problems of the nervous system, immune system, etc. The light source of the atomic absorption spectrometer emits a characteristic spectral line of a specific element, and when the characteristic spectral line passes through the atomizer, the characteristic spectral line is absorbed by ground state atoms, and the content of the element in a sample is determined by detecting the intensity of the absorbed light. The method is suitable for quantitative analysis of various metal elements, such as copper, zinc, lead, cadmium, chromium and the like, and has wide application in soil heavy metal detection. The detection device for the metal content of the soil in the prior art can influence the detection of the stone particles and other impurities in the soil on the metal content, is inconvenient to screen out the stone particles and other impurities, and the existing detection device for the metal content of the soil can influence the screening effect on the soil after the screen frame is damaged after being used for a long time, so that the screen frame is inconvenient to detach and replace.
