AI Technical Summary

Problems solved by technology

[0012] In the above-mentioned detection methods, the instruments and equipment used are relatively precise, expensive, and large in size, and they need to be fixed and used after installation and commissioning in the laboratory, and cannot be carried around for use when going out. When detecting the content of heavy metals in soil, on-site sampling is required Finally, it is sent to the laboratory for complex pretreatment and heterotopic detection and analysis, which is time-consuming and inconvenient, and cannot be used for on-site rapid detection

Abstract

The present invention provides a kind of on-the-spot detection device that rapidly detects soil heavy metal content completely different from the prior art principle, and detection device comprises: sensor, programmable signal generator, current sampler, voltage sampler, instrument amplifier, A / D converter, interface circuit, MCU, input device, temperature control module, power supply module; said sensor is also built-in electric heater and thermocouple; during detection, the sensor is filled with collected soil samples. The soil heavy metal content can be inverted from the shape of the Cp-f curve and Tan(Delta)-f curve of the measured soil sample.

Description

Technical field[0001]The invention relates to a detection device for quickly detecting the content of heavy metals in soil on site.Background technique[0002]Soil heavy metal pollution refers to the phenomenon that heavy metals are brought into the soil due to natural reasons or human activities, causing the content of heavy metals in the soil to be significantly higher than the background value, and causing existing or potential soil quality degradation, ecological and environmental degradation. There are a wide range of sources of heavy metals in soil, mainly including atmospheric dust, sewage irrigation, improper stacking of industrial solid waste, mining activities, pesticides and fertilizers. Any industry that uses heavy metals and materials containing heavy metals as raw materials may emit heavy metals during the production process. If they are not handled properly, they will cause environmental pollution.[0003]Heavy metal pollution in the soil seriously endangers human health....
