AbolishedMethods for chemical analysis of limestone and dolomite - Part 3: The determination of aluminium oxide content - The chrome azurol S spectrophotometric method and the complexometric titration method
石灰石及白云石化学分析方法 第3部分：氧化铝含量的测定 铬天青S分光光度法和络合滴定法
Application Summary AI generated
This standard specifies two methods for determining aluminum oxide content in limestone and dolomite: the chrome azurol S spectrophotometric method for low concentrations and the complexometric titration method for higher concentrations. It is applied in the mining and mineral processing industries for quality control and chemical analysis of these carbonate rocks, which are used as raw materials in cement, steelmaking, and construction. The standard ensures accurate measurement of alumina levels, critical for assessing material suitability and optimizing industrial processes.
