| titleOfInvention | A kind of analysis and detection method of aluminum element in magnesium aluminum hydrotalcite |
| abstract | The invention relates to a method for analyzing and detecting aluminum elements in magnesium-aluminum hydrotalcite, comprising the following steps: dissolving a magnesium-aluminum hydrotalcite sample in a beaker by using nitric acid or hydrochloric acid, and then transferring it to a volumetric flask for constant volume; Pipette 10 mL of the sample solution and place it in a conical flask, add disodium EDTA standard titration solution to complete the complexation of metal ions; heat and boil, then cool to room temperature; add acetic acid-sodium acetate buffer solution, dropwise add two cresol orange indicator; then add an appropriate amount of pure water, and ammonia water to adjust the pH of the solution; titrate the sample solution with zinc chloride standard titration solution to light pink as the end point, and calculate the analysis result. The analysis and detection method of the present invention eliminates the interference factors of other metal elements, requires less reagents, is simple and easy to analyze and detect the aluminum element in the sample, has a short process, high efficiency, high accuracy of analysis results, and high reliability. It has good performance and can effectively solve the problems of many reagents required, high cost, long process and low work efficiency in the prior art. |
