Calibration and Wireless Data Transfer System of Soil's Heavy Metals

The issue of heavy metal contamination of soil cannot be ignored because leakage or unauthorized discharge of waste gas, liquid, and slag from important industrial sites like smelting, chemical, coking, and oil and gas extraction can result in heavy metal contamination of soil and indirectly cause irreversible damage to the human body. Implementing real-time soil heavy metal monitoring can efficiently address the issue of heavy metal concentration exceeding early warning and carry out the necessary remediation activities. It is generally known that X-fluorescence spectrometry may be used to identify heavy metals in soil. It is primarily utilized in laboratories to measure dry soil samples, though. When measuring soil in the field, moisture can have a significant impact on the equipment's measurement outcomes, which can cause a miscalculation of the level of heavy metal contamination. The moisture correction model is researched through experiments to create a soil heavy metal correction online monitoring system, which includes an X-fluorescence analyzer, sensors that can measure soil acidity and alkalinity, moisture content, and temperature, as well as a 4G wireless data transmission module, in order to address the effect of moisture. In order to offer data support for early warning, the system is implanted with a moisture correction model, and the corrected detection data are delivered to the early warning platform through a wireless data transmission module. Realized quantitative online monitoring of soil heavy metals with high detection accuracy.
