1. A method of making an anionic sorption agent comprising:
providing a pseudo-boehmite base or glycol-boehmite base; and
contacting the pseudo-boehmite base or glycol-boehmite base with a modifying composition comprising a metallic ion to form a modified pseudo-boehmite base or glycol-boehmite base comprising an anionic sorption agent comprising having cationic metal ion sites;
wherein the contacting includes a surface adsorption, ion exchange, or intercalation reaction.
