Introduction
GB/T 8151.25-2023 Determination of Indium Content in Zinc Concentrate - Flame Atomic Absorption Spectrometry is a Chinese national standard that provides guidelines for the chemical analysis of indium content in zinc concentrate using flame atomic absorption spectrometry.
Indium is a rare metal widely used in various high-tech industries such as electronics and solar energy. Its accurate determination in zinc concentrate is crucial for quality control and resource management.
This standard specifies the sampling methods, sample preparation procedures, and instrumental parameters required for the analysis. The flame atomic absorption spectrometry technique employed in this standard offers high sensitivity and precision in quantifying indium content.
The measurement principle involves atomizing the sample in a flame and measuring the absorption of indium-specific wavelengths of light. The concentration of indium is then calculated based on the absorption intensity.
The standard also provides detailed procedures for calibration, quality control, and data analysis to ensure reliable and accurate results.
By following the guidelines outlined in GB/T 8151.25-2023, laboratories and industries can effectively determine the indium content in zinc concentrate, facilitating quality assessment and traceability in the production process. This standard contributes to the standardization and harmonization of indium analysis methods, thereby promoting the development and application of indium-related industries.
