Abstract: Apparatus, materials, and methods for removing ammonia from fluid using metal hydroxides (e.g. zinc hydroxide) and metal cation loaded media (e.g. zinc loaded ion exchange resins); the metal hydroxides and metal cation loaded media may be regenerated with a weak acid (pKa between 3 and 7). Alternatively, ammonia is removed from fluids by using H2SO4 and ZnSO4 and metal cation loaded media; the metal cation loaded media may be regenerated with H2SO4 and ZnSO4; the ammonia containing H2SO4 and H2SO4 may be concentrated as necessary to form (NH4)2SO4.ZnSO4.6H2O (ammonium zinc sulfate hexahydrate) crystals. These crystals are removed from the mother liquor and heated to temperatures exceeding 200° C. releasing NH3 and H2O vapor upon the decomposition of the crystals.

Abstract: In accordance with the present invention, an improved bifunctional cation-exchange composition has been formed which comprises synthetic resin support particles and both crown ether and non-crown ether functional groups attached thereto. The compositions of the present invention provide for novel, enhanced cation separation capabilities and, depending upon the type of functional groups employed, permit effective separation of cations which elute at approximately the same time off standard and commonly used cation-exchange columns. The presently described bifunctional cation-exchange compositions also permit the effective separation of one cation from a mixture comprising another cation that is present at a significantly greater concentration. Formed articles and methods employing the bifunctional cation-exchange composition are also provided.

Abstract: A process for removing ions of dissolved heavy metals and complex heavy metals comprises provides a treatment zone in which is contained an extraction material having an activated surface that has an affinity for heavy metal ions and complex heavy metal ions. The activated surface is the reaction product of a polyamine with a covalently anchored trifunctional hydrocarbyl silyl that yields non-crosslinked amino groups to which functional chelator groups can be covalently attached. The activated surface of the extraction material is formed by first hydrating the extraction material surface and then silanizing the hydrated surface with a short chain trifunctional silane having a hydrocarbon substituent containing 1-6 carbon atoms and a terminal leaving group, and then reacting a polyamine with the hydrocarbylsilyl from the silanization of the hydrated surface so as to form an aminohydrocarbyl polymer covalently bound to the extraction material surface. The extraction material surface yields amino groups that are available for bonding to chelator groups. As thus formed, the polymer may be alkylated with a carboxyl or sulfur containing alkylating reagent on at least some of the amino groups to enhance and specialize the chelating ability of the extraction material's activated surface.
