Description

Technical Field

[0001] This utility model relates to the field of soil testing technology, specifically to a rapid detection device for metal components in soil sediments. Background Technology

[0002] With rapid industrialization and urbanization, and increasing reliance on agricultural chemicals, heavy metals and other toxic elements have caused serious environmental problems by polluting soil. Soil sediment metals generally refer to metallic elements present in soil and sediments. In the industry, elements with a density of 5 g / cm³ or higher are generally defined as heavy metals, including commonly used industrial elements such as mercury, manganese, zinc, lead, and molybdenum.

[0003] The detection of metal components in soil sediments generally employs X-ray fluorescence spectroscopy. This method utilizes primary X-ray photons or other microscopic ions to excite atoms in the analyte, causing them to produce fluorescence (secondary X-rays) for analysis of material composition and chemical state. Currently, in the process of detecting metal components in soil sediments, the soil sample needs to be poured into a sample tube and individually clamped for testing. This method is inefficient, and the presence of many particulate matter in the soil sample affects the accuracy of metal component detection. Utility Model Content
