    • A process of recovering cesium ions from mixtures of ions containing them and other ions, e.g., a solution of nuclear waste materials, which comprises establishing a separate source phase containing such a mixture of ions, establishing a separate recipient phase, establishing a liquid membrane phase in interfacial contact with said source and recipient phases, said membrane phase containing a ligand, preferably a selected calixarene as depicted in the drawing, maintaining said interfacial contact for a period of time long enough to transport by said ligand a substantial portion of the cesium ion from the source phase to the recipient phase, and recovering the cesium ion from the recipient phase. The separation of the source and recipient phases may be by the membrane phase only, e.g., where these aqueous phases are emulsified as dispersed phases in a continuous membrane phase, or may include a physical barrier as well, e.g., an open-top outer container with an inner open-ended container of smaller cross-section mounted in the outer container with its open bottom end spaced from and above the closed bottom of the outer container so that the membrane phase may fill the outer container to a level above the bottom of the inner container and have floating on its upper surface a source phase and a recipient phase separated by the wall of the inner container as a physical barrier. A preferred solvent for the ligand is a mixture of methylene chloride and carbon tetrachloride.

    • A method for the removal and concentration of desired ions such as Pd(II), Ru(III), Pd(IV), Au(III), Au(I), 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 sulfur and electron withdrawing group containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The sulfur and electron withdrawing group 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 sulfur and electron withdrawing group containing ligand portion of the compound. The process is useful in removing desired or unwanted ions from acidic waste streams, metal refining streams, and other industrial or environmental streams. The invention is also drawn to the sulfur and electron withdrawing group containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

    • Compositions of matter are disclosed comprising nitrogen containing hydrocarbons which are modified with at least one of the elements selected from the group consisting of sulfur, phosphorus an arsenic, with the modified hydrocarbons being covalently bonded to trialkoxysilane. These modified hydrocarbons are further covalently bonded to a solid inorganic support such as silica to form a solid complexing agent. The complexing agents are particularly useful in a process of removing and/or concentrating certain ions, such as noble metal ions and other transition metal ions, from solutions thereof admixed with other ions by forming a complex of the desired ion(s) with the complexing agent. The solution preferably flow through a column packed with the complexing agent to form the complex of the desired ion(s). The desired ion(s) are recovered from the column by subsequently flowing a receiving liquid through the column, wherein the receiving liquid is adapted to break the complex and receive ion(s) in solution in the receiving liquid. The receiving ion(s) can then be separated from the receiving liquid if so desired.
