摘要： 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.

摘要： A method for the removal and concentration of desired ions such as Pd(II), Pt(IV), Pt(II), Pd(IV), Ru(III), Ru(II), Au(III), Os(IV), Au(I), Cu(I), Cu(II), Ag(I), and Hg(II) 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 a thiol and/or thioether aralkyl nitrogen-containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The thiol and/or thioether aralkyl nitrogen-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 thiol and/or thioether aralkyl nitrogen-containing ligand portion of the compound. The process is useful in removing desired or unwanted ions from Rh and Ir concentrates, acidic waste streams, multiple platinum group metal refining streams, and other industrial or environmental streams. The invention is also drawn to the thiol and/or thioether aralkyl nitrogen-containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material. The preferred aralkyl group is benzyl.
摘要翻译： Pd（II），Pt（IV），Pt（II），Pd（IV），Ru（III），Ru（II），Au（III），Os（IV）等去除和浓缩所需离子的方法），Au（I），Cu（I），Cu（II），Ag（I）和Hg（II），其可以含有较大浓度的其它不希望的离子（包括H +）的多离子源溶液包括使源溶液与包含通过有机间隔硅基团共价键合到固体无机载体的硫醇和/或硫醚芳烷基含氮配体的化合物接触。化合物的硫醇和/或硫醚芳烷基含氮配体部分对所需离子具有亲和性，从而形成络合物，从而从源溶液中除去所需的离子。通过使化合物与化合物的硫醇和/或硫醚芳烷基含氮配体部分相比具有对所需离子具有更大亲和力的接收溶液的体积较小的接收溶液接触，从化合物中除去所需的离子。该方法可用于从Rh和Ir浓缩物，酸性废物流，多种铂族金属精炼流以及其它工业或环境流中除去所需或不需要的离子。本发明还涉及通过间隔基团与亲水性无机固体载体材料共价键合的硫醇和/或硫醚芳烷基含氮配体。优选的芳烷基是苄基。
