Abstract

An anionic sorption agent, method for forming the anionic sorption agent and a barrier system are disclosed. The anionic sorption agent including a modified pseudo or glycol-boehmite base comprising a structure having cationic metal ion sites. The method for forming the anionic sorption agent includes providing a pseudo or glycol-boehmite base and contacting the pseudo or glycol-boehmite base a modifying composition comprising a metallic ion to form the modified pseudo or glycol-boehmite base comprising a structure having cationic metal ion sites. The barrier system includes the anionic sorption agent comprising a first barrier component comprising a modified pseudo or glycol-boehmite base comprising a structure having cationic metal ion sites and a second barrier component comprising a cationic sorption agent.

Claims (13)

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.

2. The method of claim 1 , further comprising heating the pseudo-boehmite base or glycol-boehmite base to remove water from the pseudo-boehmite base or glycol-boehmite base.

3. The method of claim 1 , wherein the modifying composition is a solution comprising metal ions selected from the group consisting of Mn, Fe, Co, Ni, Cu, Zn, and combinations thereof.

4. The method of claim 3 , wherein the cationic metal ion site includes Ni.

5. The method of claim 3 , wherein the modifying composition is NiCl 2 .

6. The method of claim 1 , wherein the providing and contacting are incorporated in a single synthesis step.

7. The method of claim 6 , wherein the cationic metal ion sites have been incorporated during the single synthesis step.

8. The method of claim 7 , wherein the single synthesis step includes forming a glycol-boehmite base in a glycol solvent.

9. The method of claim 8 , wherein the synthesis step includes providing modifying composition containing dopant ions selected from the group consisting of Y, Ga, Fe, Si, P, S, Ti, Zr, Hf, and combinations thereof.

10. The method of claim 1 , wherein the modified pseudo or glycol-boehmite base includes a surface area greater than about 160 m 2 /g.
