Soil heavy metal content estimation method and device

Abstract

The invention relates to the technical field of soil metal content estimation, and discloses a soil heavy metal content estimation method and device. The soil heavy metal content estimation device comprises an intelligent terminal detection machine, the intelligent terminal detection machine is reasonable in structure arrangement and small in size, is convenient to carry and is convenient for thereal-time detection of the sampled soil, and a system of the intelligent terminal detection machine is easy to control, the normalization processing and transmission of the test data can be completed,and in subsequent data processing, the absolute values of the measured values do not need to be considered, but only the shape of a curve obtained through measurement needs to be considered, so thatthe measurement is convenient. If the soil in a sampling area needs to be further detected, the soil can be sent to a laboratory for the subsequent detection work. In conclusion, the mobile intelligent terminal detection machine is suitable for the field on-site rapid detection, and is very simple and convenient to operate, so that the monitoring efficiency in environmental protection work is greatly improved.

Description

technical field [0001] The invention relates to the technical field of soil metal content estimation, in particular to a soil heavy metal content estimation method and device. Background technique [0002] The problem of heavy metal pollution in the production areas of agricultural products in my country has become increasingly prominent, and the enrichment of heavy metals in soil has seriously threatened the safety of ecosystems and human beings. In the process of preventing, monitoring and controlling soil heavy metal pollution, detecting the content of heavy metals in soil is a very important link. Quantitative detection and analysis techniques for heavy metals usually include: ultraviolet spectrophotometry (UV), atomic absorption (AAS), atomic fluorescence (AFS), inductively coupled plasma (ICP), X-ray fluorescence spectroscopy (XRF), inductively coupled Plasma mass spectrometry (ICP-MS). [0003] However, the above-mentioned detection methods are obtained through high...

Problems solved by technology

[0003] However, the above-mentioned detection methods are obtained through high-precision equipment detection in the laboratory. Although the concentration of heavy metals can be accurately obtained, the conditions are limited, especially for field detection in outdoor environments. It is inconvenient, time-consuming, and inconvenient to use. , thus affecting the detection efficiency

When testing the content of heavy metals in soil, it is necessary to take on-site samples and then send them to the laboratory for complex pretreatment and ex-situ detection and analysis, which is time-consuming and inconvenient, and cannot be used for rapid on-site testing
