2025新实施标准盘点：地质矿产、金属材料篇 ——共有665份新标准实施

Core Viewpoint - In 2025, the geological minerals and metal materials sectors will implement 665 new standards, focusing on analysis methods such as ICP-AES, ICP-MS, ion chromatography, and X-ray fluorescence, which will enhance mineral resource testing and the technological upgrade of metal materials research [2]. Group 1: New Standards Implementation - The new standards will include methods for determining the content of fluorine and chlorine in manganese ore using ion chromatography, and the analysis of non-rare earth impurities in rare earth metals and their oxides [4][5]. - Standards will also cover the determination of various elements in different materials, including the use of gas chromatography and mass spectrometry for analyzing oil-recycled metals and the content of sulfur in coking wastewater [5][6]. Group 2: Importance of Analytical Instruments - Analytical instruments such as ICP-AES and ICP-MS are crucial for accurately measuring trace impurities in precious metals, rare earths, and high-purity metals, ensuring material purity meets industrial standards [3]. - Ion chromatography demonstrates high flexibility in detecting fluorine and chlorine content in iron and manganese ores, while portable X-ray fluorescence significantly improves the efficiency of on-site screening of imported mineral products and steel products [3]. Group 3: Technological Advancements - The widespread application of scanning electron microscopy (SEM) and focused ion beam technology provides precise support for imaging rock micropores and metallographic structure analysis, enhancing the sensitivity and accuracy of testing [3]. - These advancements lay a solid scientific foundation for the comprehensive utilization of mineral resources and the development of new materials [3].
