The standard "GB/T 44343-2024 Determination of 22 elements in soil mass soil, acid dissolution-Inductance coupled plasma mass spectrometry" details the technical requirements and operation steps for the determination of 22 elements in soil samples by acid dissolution method. The method is suitable for homogenized soil samples and can accurately determine the total amount of elements such as lithium, beryllium, scandium, vanadium, chromium, manganese, cobalt, nickel, copper, zinc, arsenic, strontium, molybdenum, cadmium, antimony, barium, tungsten, thallium, lead, bismuth, thorium and uranium. The standard describes the acid analysis process of the sample, using a mixed system of hydrofluoric acid, nitric acid, perchloric acid and muriatic acid to transfer the target element into the solution, and then using Inductance coupled plasma Mass spectrometry for qualitative and quantitative analysis to ensure the accuracy and Reliability of the measurement results. The standard provides an important technical basis for soil mass monitoring and environment assessment.
