An anion exchange stationary phase comprises substrate particles, a based condensation polymer layer attached to the substrate particles, one or more alkylamine condensation polymer layers covalently attached to base condensation polymer layer, and a terminating condensation layer covalently attached to the alkylamine condensation polymer layer. They layers are formed from amines and polyethylene oxide where the hydroxyl groups are spaced from the amines by two carbon atoms.

The present invention relates to the extraction of lithium from liquid resources such as natural and synthetic brines, leachate solutions from minerals, and recycled products.

A system and method for the reduction of NOx and CO contaminants using an ion-exchange resin media having lower-valency ions of the transitional metal elements, such as ferrous ions, cuprous ions and/or manganese ions, such that gases containing NOx and/or CO contaminants may be passed over the media so that the contaminants are absorbed by the lower-valency ions of the transitional metal elements, the media configured so that it can be regenerated to remove the NOx and/or CO contaminants. Regeneration includes exposing the media to a heated stream of hydrogen gas or exposing the media to hydrogen ions in an electrochemical cell.

Methods for removing a target selenium entity from fluids by treating the fluid with a rare earth impregnated media containing an immobilized rare earth. The methods including obtaining a contaminated fluid comprising water and dissolved selenate; contacting the feed fluid with a rare earth impregnated media for removal of at least a portion of the selenate from the feed fluid thereby forming a treated fluid comprising less selenium than the feed fluid.
