Determination method of aluminum

Method Name
Determination of sucralfate aluminum - complexometric titration method
Application scope
The complexometric titration method is used to determine the aluminum content in sucralfate, which is suitable for the determination of aluminum content in sucralfate.
Method principle
Take an appropriate amount of the test sample, dissolve, dilute, and neutralize it. Add acetic acid ammonium acetate buffer solution and precisely add ethylenediamine tetraacetate disodium titration solution (0.05mol/L). Boil for 3-5 minutes and let it cool to room temperature. Every 1mL of ethylenediamine tetraacetate sodium titrant (0.05mol/L) is equivalent to 1.349mg of aluminum, calculated as.
