Embodiment Construction
[0052] The preferred embodiments will be described in detail below in conjunction with the accompanying drawings. It should be emphasized that the following description is only exemplary and not intended to limit the scope of the invention and its application.
[0053] The idea of solving the problem of the present invention is to use the visible light and near-infrared transmission spectrum of the colorimetric solution to be tested to invert the content of heavy metal lead in the soil or water environment, that is, using a light-emitting diode bulb with a corresponding wavelength, the light emitted by the light source first passes through the The corresponding optical filter (the bandwidth of the optical filter is 10nm), and then the solution to be tested after the colorimetric reaction (referred to as the colorimetric solution) reaches the photoelectric detection chip, calculates the value of the transmittance, and then inverts to obtain the Measure the content of heavy me...

Abstract
The invention discloses the field of a heavy metal detection technology, and relates to a device and a method for rapidly detecting heavy metal lead pollution in soil or water. The device concretely comprises a black box module, a microcomputer module, a power module and a display module, wherein the block box module, the display module and the power module are respectively connected with the microcomputer module; the black box module comprises a black box, a fixed black box groove, a light source, an optical filter, an optical filter rack, a cuvette, a groove and a photoelectric detection chip; the cuvette is arranged in the middle of the black box; the light source and the optical filter are arranged at the left side of the black box; the photoelectric detection chip is arranged at the right side of the black box correspondingly to the light source; the content of heavy metal lead in soil or water environments is inverted by visible light of a colorimetric solution to be detected and a near infrared transmittance spectrum. The device and the method are capable of rapidly and accurately measuring the heavy metal lead pollution in the soil or water environments, so that the sufficient basis is provided for the detection on the soil or water environments.
Description
technical field [0001] The invention relates to the technical field of heavy metal detection, in particular to a rapid detection device and method for heavy metal lead pollution in soil or water. Background technique [0002] Heavy metals refer to metals with a specific gravity above 5, such as copper, lead, zinc, nickel, cadmium, chromium, mercury, bismuth, tin, antimony, niobium, molybdenum, etc. In general, heavy metals do not reach the harmful level, but with the progress of society and the deepening of industrialization, the toxic and harmful heavy metals such as lead, cadmium, mercury, and chromium entering the soil, atmosphere and water are increasing day by day, exceeding the normal range will cause heavy metal pollution. For environmental pollution, after heavy metals enter the human body with food, they will be amplified through the food chain and cause chronic damage to the body. The heavy metals entering the human body will accumulate over a long period of time a...
