Rapid tester for lead element in soil

Abstract

The invention provides a rapid tester for lead element in soil, which comprises a fluorescence spectrometer and a man-machine interaction touch screen, the fluorescence spectrometer is sleeved with a box body, the top of the fluorescence spectrometer is fixedly provided with a fixing cover, the man-machine interaction touch screen is located on the surface of the fixing cover, a fixing mechanism is arranged between the box body and the fixing cover, and the fixing mechanism is located on the surface of the fixing cover. A measuring cavity, a control cavity and a material suction cavity are formed in the box body. Through the arrangement of the inserting rod with the graduated scale, the rotating rod, the smashing blade, the driving mechanism, the material suction pump and other mechanisms, the sampling position can be accurately determined, soil at the sampling position is smashed and conveyed to the fluorescence spectrophotometer through the material suction pump to be measured, deep soil can be conveniently measured, the sampling position is accurate, and the sampling accuracy is high. Through the arrangement of structures such as a fixing mechanism, a switch cover and a handle, the whole fluorescence spectrophotometer can be taken down, so that the surface soil can be conveniently measured, and the instrument is more flexible and convenient to use.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to a rapid detector for lead in soil. Background technique [0002] Fluorescence spectrometer, also known as fluorescence spectrophotometer, is an instrument for qualitative and quantitative analysis. Through the detection of fluorescence spectrometer, the excitation spectrum and emission spectrum of substances can be obtained. Spectrum, quantum yield, fluorescence intensity, fluorescence lifetime, Stokes shift, fluorescence polarization and depolarization characteristics, and information on fluorescence quenching. It has high sensitivity and good stability. It is an important instrument for detecting heavy metals and is widely used. It is used in the detection of heavy metal elements such as mercury and lead in soil. [0003] However, the existing soil measuring instruments generally can only detect the metal content of the surface soil. The detection is carried out by a ha...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a rapid measuring instrument for lead in soil, which solves the problem that such soil measuring instruments in the prior art can only detect the metal content of the surface soil, and the handheld fluorescence spectrometer is used to approach the To test the soil, for the soil in the deep part, it is necessary to dig it with a shovel, and then use the sampling shovel to sample the soil at the excavated part before it can be verified by the soil verification instrument. The operation is not convenient, and it is time-consuming and laborious. not precise enough
