الإجراء التجريبي

To 459 parts water, were added 140 parts sodium aluminate (24.0% Al2O3). Next 255 parts liquid Alum were added under high mixing at 20° C. over 1/2 hour. The pH was 5.6 and after 3/4 hour of mixing 445 parts of liquid Alum were added, and the temperature was kept at 20° C. for an additional 11/2 hour. It was then increased to 58° C. over 11/4 hour and held for 1/2 hour at which time the mixture became totally clear. The product was cooled and showed a basicity of 52.7% and 7.3% Al2O3.
