Introduction
GB/T 6150.18-2023 "Chemical Analysis Methods for Tungsten Ore - Part 18: Determination of Barium Content by Inductively Coupled Plasma Atomic Emission Spectroscopy" is a standard that outlines the procedure for measuring the barium content in tungsten ore using the Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES) method. This standard provides a reliable and accurate method for determining the barium content, which is an essential parameter for evaluating the quality and purity of tungsten ore. The ICP-AES technique allows for the simultaneous measurement of multiple elements, making it a highly efficient and time-saving method for chemical analysis. The procedure outlined in this standard involves the preparation of the sample, which includes grinding, homogenizing, and drying. The sample is then dissolved in a suitable acid solution, and any impurities are removed through filtration. The resulting solution is then introduced into the ICP-AES instrument, where the barium content is determined by measuring the characteristic emission lines of barium atoms. By following the guidelines provided in GB/T 6150.18-2023, laboratories can ensure the accuracy and repeatability of their barium content measurements in tungsten ore samples. This standard is applicable to both research and industrial laboratories involved in the analysis of tungsten ore, enabling them to meet the requirements of quality control and product development.
