Soil heavy metal detection device

Abstract

The invention discloses a soil heavy metal detection device, comprising a shell body and a drill bit, wherein the bottom end of the shell body is movably connected with the drill bit; an optical spectrum analyzer is arranged in the shell body and is fixed on the periphery of the inner wall of the shell; a connecting pipe is arranged between the bottom end of the optical spectrum analyzer and the bottom of the shell body; a display instrument is connected with the right side of the shell body. The soil heavy metal detection device has the beneficial effects that by being provided with a sharp end, the soil heavy metal detection device can conveniently drill into a harder soil layer; a radiometer is used for detecting whether the content of heavy metals in the soil exceeds the standard or not; a probe and the optical spectrum analyzer are arranged for detecting the composition and content of the heavy metals; by being provided with a photodiode and a light-emitting diode, the soil heavymetal detection device is ingenious in structure and reasonable in light source and transmission mode; the soil heavy metal detection device is simple in structure, high in practicality and easy to disassemble and carry.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a soil heavy metal detection device. Background technique [0002] Soil environmental monitoring refers to determining the environmental quality (or pollution degree) and its changing trend by measuring the representative values ​​of factors affecting the soil environmental quality. What we usually call soil monitoring refers to soil environmental monitoring, which generally includes technical content such as spot sampling, sample preparation, analysis methods, result characterization, data statistics, and quality evaluation; among the soil inorganic pollutants, heavy metals are more prominent, mainly Since heavy metals cannot be decomposed by soil microorganisms, they are easy to accumulate and transform into more toxic methyl compounds, and some even accumulate in the human body at harmful concentrations through the food chain, seriously endangering human health. Most of the...

Problems solved by technology

Most of the existing technologies are digested by strong acid, and then analyzed by a spectrometer, but the detection period is long, and most of the current soil detection needs to be tested on the spot. The traditional detection method has certain detection difficulties.
