ABSTRACT:
Formation of hydrous alumina in the reticules of a weak-base anion exchange resin, wherein AlCl.sub.3 has been precipitated as hydrous alumina by reaction with ammonia, is improved by employing a subsequent treatment with HCl or with NH.sub.4 Cl and HCl to convert the exchange resin to the chloride form, thereby increasing the reticular volume of the resin, thus permitting subsequent precipitation of additional hydrous alumina therein.
