Abstract
Solution experiments were conducted in which basic aluminum sulfates were precipitated from dilute solutions of various concentrations of sulfate and potassium at different pHs. Aging of precipitates at 50°C for 18 weeks resulted in crystalline precipitates of gibbsite, basaluminite, alunite, or mixtures of these minerals. The results suggest that sulfate in acid soil solutions will react in a similar manner with Al to form a sparingly soluble aluminum-hydroxy-sulfate compound.
