GB/T 24229-2009 Determination of aluminum content in chromium ore and chromium concentrate by complexing Titrimetric method. Applicable to all kinds of chromium ore and chromium concentrate samples. Using reagents that can form stable complexes with aluminum ions, under specific conditions, react with aluminum ions in the sample solution, and determine the titration endpoint by the change of indicator Color or potential change. The standard specifies the required instruments, such as Burette, etc., and specifies the preparation of reagents. Detailed description of Sample Handling steps, including the dissolving of ores and concentrates, and the masking of interfering elements. Standardized titration process. According to this standard, the aluminum content can be accurately determined, providing key data support for product mass evaluation and industrial production.
