摘要： 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.

摘要： 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.

摘要： A method is disclosed for the quantitative removal and concentration of desired molecules or ions, such as gases, anions and amino acids, from a source solution which may contain larger concentrations of other molecules. The method comprises bringing the source solution into contact with a solid cation-ligand-matrix consisting of a cation complexed to a ligand molecule covalently bonded to a matrix consisting of an organic spacer bonded to a solid inorganic support through a silicon atom. The cation has an affinity for the desired molecules to form a complex between the desired molecules and the cation portion of the solid cation-ligand-matrix at binding sites initially held by H.sub.2 O or other weakly coordinated ligands or via ion pairing. The desired molecule complex is broken releasing either the desired molecules or desired molecules complexed with the cation by contacting the solid cation-ligand-matrix-desired molecule complex with a much smaller volume of a receiving solution in which said desired molecules are soluble. The concentrated ions or molecules thus removed may be analyzed and/or recovered by known methods. The process is useful in measuring the concentrations of molecules originally present at parts per billion levels; in the removal of low levels of toxic molecules such as ammonia or anions such as chromate from potable and saline water; in the preparation of ultrapure salts and gases; and in the recovery of valuable molecules present in low concentrations as in the separation of amino acids, etc.

摘要： A method for the removal, separation, and concentration of Rh, Ir, and/or Ru from a source solution which may contain larger concentrations of other ions including H.sup.+ comprises bringing the source solution into contact with a compound comprising a polyalkylene-polyamine-containing ligand covalently bonded through an organic spacer silicon grouping to a solid inorganic support. The ligand portion(s) of the compound has affinity for complexed anionic species of Rh, Ir, and/or Ru thereby removing them from the source solution. The Rh and/or Ru are first selectively removed from the compound through contact with a much smaller volume of a first receiving solution which changes the Rh and/or Ru speciation to have no affinity for the ligand portion of the compound. The Ir is then removed from the compound through contact with a much smaller volume of a second receiving solution having a greater affinity for the Ir than the ligand portion of the compound or having a greater affinity for the ligand portion of the compound than the Ir species. The concentrated ions thus removed may be further separated and recovered by known methods. The process is useful in the recovery and refining of the valuable Rh and Ir from a variety of sources. The invention is also drawn to the particular highly stable branched polyalkylene-polyamine-containing ligands covalently bonded through a spacer grouping to a hydrophilic inorganic solid support material.

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.

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 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.

摘要： 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.
