Abstract: A method for the removal and concentration of desired ions such as Sb.sup.3+, Zr.sup.4+, Zn.sup.2+, Pu.sup.4+, Hf.sup.4+, Cu.sup.2+, Ni.sup.2+, Fe.sup.3+, Cd.sup.2+, Ag.sup.+, and Hg.sup.2+ from a multiple ion source solution which may contain larger concentrations of other undesired ions including H.sup.+ comprises bringing the source solution into contact with a compound comprising an aminoalkylphosphonic acid containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The aminoalkylphosphonic acid containing ligand portion(s) of the compound has an affinity for the desired ions to form a complex thereby removing the desired ions from the source solution. The desired ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired ions than does the aminoalkylphosphonic acid containing ligand portion of the compound. The process is useful in removing desired or unwanted ions of Sb(III) from acidic waste streams, streams containing concentrated Cu(II), Ni(II), Zn(II), and Ag(I), and also the removal of Zr(IV), Pu(IV) and Hf(IV) from nitric acid solutions containing large amounts of other ions as well removal of unwanted ions from other industrial or environmental streams.

Abstract: The present disclosure relates to improved methods for the preparation of aluminum phosphate molecular sieves and faujasite-type zeolites having stably encapsulated multidentate metal chelate complexes. This is achieved through direct incorporation of a selected multidentate chelate complex into the molecular sieve or zeolite reaction admixture prior to crystallization, allowing the admixture to react under conditions appropriate for the selected molecular sieve or zeolite, followed by preparation of the resultant molecular sieve-metal chelate complex in a highly crystalline form.

Abstract: Dipicolylamine (DPA) is chemically bound to the surface of a silicate, forming a solid phase particle without substantially decreasing the affinity constant of the DPA for certain ions. Then, the solid phase particle is contacted with the solution, thereby binding an ion to the particle. Subsequently the ion can be stripped from the ligand by treatment with a complexing agent or acid.

Abstract: A method is disclosed for the quantitative removal and concentration of desired transition metal ions from a source solution which may contain larger concentrations of other metal and H.sup.+ ions. The method comprises bringing the source solution into contact with a compound comprising a pyridine containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The pyridine portion(s) of the compound has an affinity for the desired metal ions to form a complex thereby removing the desired metal ions from the source solution. The desired metal ions are removed from the compound by contacting the compound with a much smaller volume of a receiving solution having a greater affinity for the desired metal ions than does the pyridine ligand portion of the compound. The concentrated metal ions thus removed may be recovered by known methods. The process is useful in removing unwanted metal ions from water streams and in the treatment of waste streams such as those containing metal ions from emulsions found in the treatment of photographic and x-ray films. The invention is also drawn to novel intermediates comprising pyridine containing ligands covalently bonded through a spacer grouping to a silane and to the final compounds formed by reacting the intermediates with a hydrophilic inorganic solid support material.
