Scope

Scope: This standard specifies the methodological principles, equipment and materials, testing methods, and usage forms for measuring heavy metal elements in soil using energy-dispersive X-ray fluorescence spectrometry. This standard is applicable to the rapid screening of heavy metal elements (copper, zinc, lead, nickel, chromium, and arsenic) in soil. Main technical content: When the atoms of elements contained in soil samples are irradiated by high-energy X-rays, they emit characteristic X-ray spectra with certain energy. According to the principle that the pulse height of the output signal from the semiconductor detector is proportional to the energy of the incident X-ray photons, when the semiconductor detector detects the characteristic X-ray spectra of soil samples, the channels of the multichannel analyzer count simultaneously, enabling the simultaneous measurement of multiple elements. Qualitative and quantitative analysis is carried out by detecting the energy positions and intensities of different characteristic X-rays.
