Abstract: An improved anion-exchange process for the removal and recovery of trace quantities of chromates from water. The process utilizes a bed of basic anion-exchange resin and the combination of upflow exhaustion of the chromates from the water and downflow regeneration of the resin. Efficient recovery of chromates is accomplished while virtually eliminating chromate leakage during the initial portion of the exhaustion operation. Regeneration can be accomplished without the use of strong, expensive chemicals.

Abstract: An anion exchange membrane is made by mixing 2 trifluoroMethyl Ketone [nominal] (1.12 g, 4.53 mmol), 1 BiPhenyl (0.70 g, 4.53 mmol), methylene chloride (3.0 mL), trifluoromethanesulfonic acid (TFSA) (3.0 mL) to produce a pre-polymer. The pre-polymer is then functionalized to produce an anion exchange polymer. The pre-polymer may be functionalized with trimethylamamine in solution with water. The pre-polymer may be imbibed into a porous scaffold material, such as expanded polytetrafluoroethylene to produce a composite anion exchange membrane.
