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

DWPI Title: Anionic sorption agent for use in barrier system for water purification, comprises base comprising structure having cationic metal ion sites, where base is modified pseudo-boehmite base and modified glycol-boehmite base
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: Anionic sorption agent for use in barrier system (claimed) that is utilized for water purification.
Advantage: The anionic sorption agent is simple and/or inexpensive for removing anionic pollutants such as arsenic, at high rate.
Novelty: Anionic sorption agent comprises a base comprising a structure having cationic metal ion sites, where the base is a modified pseudo-boehmite base and modified glycol-boehmite base.
