Abstract

The invention discloses a rapid detector for detecting soil heavy metal. The detector comprises a detector body, and the detector body comprises an X-ray tube, a silicon drift detector, a housing anda processor installed in the housing. The outer wall of the housing is fixedly provided with a display screen, and the processor is electrically connected with the X-ray tube, the silicon drift detector, and the display screen. A transverse plate is fixed to the outer wall of the housing. The X-ray tube is mounted at the top of the transverse plate. A transparent soil containing vessel is fixed tothe top of the X-ray tube, the silicon drift detector is arranged above the X-ray tube, and a mounting plate is fixed at the position, located above the transverse plate, of the outer wall of the housing. The bottom of the mounting plate is connected with a base plate through a base plate driving device, and the silicon drift detector is mounted at the bottom of the base plate. The invention hasthe beneficial effects of convenience in carrying and high practicability.

Description

technical field [0001] The invention belongs to the technical field of soil detection, and in particular relates to a rapid detector for soil heavy metal detection. Background technique [0002] Heavy metals in the soil absorb high-energy X-rays, causing the inner electrons of heavy metal atoms to be excited to become free electrons after absorbing the energy of X-rays. The electrons in the outer shell then fill the vacancies of the electrons in the inner shell, which is the electronic transition, and the electronic transition emits X-ray fluorescence. The energy of electronic transition is equal to the energy difference between two electronic energy levels, and the energy or wavelength of X-ray fluorescence is characteristic and has a one-to-one correspondence with elements. Therefore, as long as the energy or wavelength of the X-rays emitted to the heavy metals in the soil can be used to determine the type of heavy metals contained in the monitored soil. [0003] In view...
