Abstract
Solution experiments were conducted in which basic Al sulfates were precipitated from dilute solutions of various concentrations of sulfate and K at different pH. Aging of precipitates at 50.degree. C for 18 wk resulted in crystalline precipitates of gibbsite, basaluminite, alunite, or mixtures of these minerals. Sulfate in acid soil solutions will react in a similar manner with Al to form a sparingly soluble aluminum-hydroxy-sulfate compound.This publication has 2 references indexed in Scilit:
