Abstract

Hydrolysis of aluminum sulfate and potash alum in the presence of an ammonium sulfite additive in the temperature range T boil-200°C was studied. A possible reaction mechanism was suggested. The composition and structure of the precipitates formed were determined and certain differences in their morphology were noted. Recommendations for practical implementation of the method of hydrolytic recovery of aluminum from solutions of its sulfate salts were given.
