Patent ID: 7906456

Claim:
A method of producing a filtration media having a chemical reagent comprising the steps of: mixing H 2 O, KMnO 4 , and at least one salt adding ions or ionic compounds selected from the group consisting of Na + , Li + , K + , NH 4 + , Cl − , SO 4 2− , BO 3 2− , CO 3 2− , PO 4 3− NO 3 − and combinations thereof or from the group consisting of Na + , Li + , K + , NH 4 + , Mg 2+ , Ca 2+ , Cl − , BO 3 2− , NO 3 − and combinations thereof forming an impregnating solution; heating said impregnating solution; combining an activated alumina support with said impregnating solution in an amount sufficient to form a coherent mass; mixing and heating said impregnating solution and said activated alumina support; and curing said impregnating solution and said activated alumina support forming said coherent mass; wherein said at least one salt has NaNO 3 and Na 3 PO 4 .
