Abstract

The invention relates to an X-ray-based typical contaminated site soil heavy metal detection system and method. The X-ray-based typical contaminated site soil heavy metal detection system comprises ashell, a light transceiver, a component analysis module, a data processing module, a humidity detection module, a detection button, a display screen, a key module and a storage card slot. According tothe invention, a humidity influence compensation algorithm is set in the data processing module, a qualitative and quantitative calculation mathematical model is established, and original data collected by the light transceiver is subjected to modular calculation to complete data correction, so that the influence of soil humidity on the measurement of the metal content by the X-ray fluorescence spectrometry is reduced.

Description

technical field [0001] The invention relates to the technical field of soil detection, in particular to an X-ray-based soil heavy metal detection system and method in a typical polluted site. Background technique [0002] Soil is the environment for plants to survive, and it contains many kinds of elements in different forms. The composition and content of elements in soil determine soil fertility and environmental quality, including beneficial elements needed for plant growth and harmful elements represented by heavy metals. In the early days, my country's soil environmental monitoring focused on the detection of soil fertility. In recent years, with the intensification of heavy metal pollution in soil, relevant departments have gradually shifted their focus to the detection of soil environmental pollution, especially heavy metal pollution in soil. Through the rapid and effective determination of heavy metals in the soil, it is possible to understand the pollution status o...
