Sorption agent, method of making a sorption agent and barrier system

DWPI Title: Method of making an anionic sorption agent used for removal of anionic pollutants, involves contacting the pseudo or glycol-boehmite base with a modifying composition comprises a metallic ion to form a modified pseudo or glycol-boehmite base comprising a structure having cationic metal ion sites
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.
Use: Method of making an anionic sorption agent used for removal of anionic pollutants.
Advantage: Method of making an anionic sorption agent with increased sorption and/or removal of anionic pollutants.
Novelty: Method of making an anionic sorption agent involves contacting the pseudo or glycol-boehmite base with a modifying composition comprising a metallic ion to form a modified pseudo or glycol-boehmite base comprising a structure having cationic metal ion sites.
