Determination of Caustic Hydroxide,Sodium Carbonate and Alumna in Sodium Aluminate Solutions

With automatic electric potential titrantion and sodium gluconate as the complexing agent,which can coordinate to the aluminum in the sodium aluminate solution, followed by the replacement of aluminum in sodium aluminate solution with KF and the same equivalent weight of OH~- to that of aluminum was released, the contents of caustic hydroxide,sodium carbonate and alumina in the sodium aluminate solutions can be continuously determined. It makes the analysis simple, fast and the result is satisfied.
