Preparation of Sodium Aluminate From Basic Aluminium Sulfate

Aug 01, 2006· The basic aluminum sulfate used in this work was obtained by precipitation in homogeneous solution by heating an aqueous solution of aluminum sulfate and ammonium bisulfite. This latter solution was obtained by passing sulfur dioxide through an ammonium hydroxide solution until a solution pH 4 was obtained.
