    摘要: 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.

    摘要: A resin/aluminate composite which has been substantially loaded with Li.sup.+ values by being contacted with a contaminated, Li.sup.+ -containing aqueous solution, is pre-washed with a substantially pure, concentrated NaCl brine to remove the contaminants without removing the Li.sup.+ values, then is washed with water to leach out much, but not all, of the Li.sup.+ values. The resin/aluminate composite comprises a macroporous anion exchange resin having crystalline LiX.2Al(OH).sub.3 dispersed therein, where X is halide.
