| titleOfInvention | Detection method of metal aluminum content in aluminum slag |
| abstract | The invention relates to a method for detecting the content of metallic aluminum in aluminum slag, comprising the following steps: S1, taking a sample of aluminum slag, crushing and sieving to obtain a sample to be tested; S2, mixing the sample to be tested with methanol, Liquid bromine is added dropwise, and after the dropping is completed, the temperature is kept at 45°C to 55°C until the sample to be tested is fully dissolved to obtain a mixed solution; wherein, the amounts of the sample to be tested, the methanol and the liquid bromine are used. The ratio is (0.5-1) g: (15-20) mL: (2-5) mL; S3, filter the mixed solution and rinse the filter residue with ethanol to obtain a filtrate, which is diluted with water until the filtrate is neutral Set the volume to obtain the solution to be analyzed; S4, take an appropriate amount of the solution to be analyzed, add hexamethylenetetramine and excess EDTA solution, after the complexation reaction is complete, use xylenol orange as an indicator, and use zinc standard solution Titrate excess EDTA to the titration endpoint. The method has high accuracy, good reproducibility, and is simple and easy to implement. |
