Analysis of Bayer aluminate liquors using thermometric titration

Thermometric titrimetry is ideally suited for industrial process control analysis. The thermometric sensor requires virtually no maintenance and because endpoints are located from the second derivative of the titration solution temperature curve, no calibration is required. Moreover, titrations are typically fast, leading to high analytical productivity. An illustration of the utility of the technique is the high-precision automated analysis of total hydroxyl, carbonate and alumina values in sodium aluminate solutions in the refining of alumina by the “Bayer Process”. Pure sodium aluminate solutions are also produced for use in water purification, the manufacture of paper and of synthetic zeolites; the method described here is also suitable for these solutions.
