Abstract

Ammonium bisulfite as a precipitating agent was used to synthesize basic aluminum sulfate (BAS) by homogeneous precipitation. Aluminum sulfate in aqueous solution was used as the raw material. High concentration of the precipitant agent promotes the formation of ammonium alunite, which was confirmed by XRD, TG/DTG and FTIR analysis. The ammonium alunite has less sulfate ions and more water than the BAS, and so, the ammonium alunite heat treated up to 1200°C produces 28 weight percent of Al2O3. In comparison the BAS generates 48 weight percent of Al2O3 as a final product. Homogeneous precipitation promotes the formation of amorphous spherical particles of basic aluminum sulfate and lamellar crystalline particles of ammonium alunite which were observed by field emission microscopy (FEM).
