摘要： The invention is a process of selectively and quantitatively removing and concentrating at least one selected ion prosent in low concentration with other ions in higher concentration in a multiple ion solution. The method comprises bringing a complexing agent for the selected ion(s) into contact with a different determined quantity of said multiple ion solution to remove and concentrate the selected ion(s) from the multiple ion solution; removing the multiple ion solution, from which the complexing agent has been removed, the selected ions from the complexing agent having the selected ion(s) complexed therewith, bringing the complexing agent complexed with selected ion(s) into contact with a determined quantity of receiving liquid to break the complex and remove the selected and concentrated ion(s) from the complexing agent therein, and determining the concentration of selected ion(s) in said receiving liquid from which the concentration of selected ion(s) in the multiple ion solution can be calculated. The metal ions in low concentration are often heavy metal ions, such as lead ions, and the process finds particularly advantageous utility in the determination of lead content in ppb in drinking water.The preferred apparatus for carrying out the process is a column packed with silica gel or silica-bonded macrocycle as the complexing agent which is preferably carried out using as the complexing agent a macrocyclic compound having at least four --A--CH.sub.2 --CH.sub.2 --groups in which A is selected from --O--, --O--CH.sub.2 --, --S--, --S--CH.sub.2 --, --N--R--, and --N--((R)--CH.sub.2 in which R is selected from H, lower alkyl and benzyl and which has a hydrocarbon side chain having an end group. ##STR1## covalently bonded to silica in which X is selected from lower alkly, benzyl, phenyl, halogen, --O--CH.sub.2, --O--C.sub.2 H.sub.5 and Si.sub..dbd..sup.-. Typical compounds within this generic definition consist of the following groups of compounds wherein the macrocycle is bonded to the silica through a hydrocarbon side chain with or without an ether oxygen: ##STR2## in which Silica is sand or silica gel.

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.

摘要： A method and composition for the concentration and removal of desired metal ions from a source solution by contacting the solution with an N-cyclic aromatic hydrocarbon-containing ligand covalently bonded to a solid support through a hydrophilic spacer of the formula SS--A--X--(L).sub.n where SS is a solid support, A is covalent linkage mechanism, X is a hydrophilic spacer grouping, L is an N-cyclic aromatic containing ligand group and n is an integer of 1 to 6. X or L combined will not contain more than two amine nitrogen atoms. There will preferably be at least four N-cyclic groups present of which pyridine, pyrimidine, pyraxine, imidazole, quinoline, isoquinoline, naphthyridine, pyridopyridine, phenanthroline are representative. The desired ions in the source solution are bound to the ligands and are subsequently separated by contacting the ligand containing compound with a smaller volume of a receiving solution that removes the bound ions for recovery in concentrated form in the smaller volume of the receiving solution.
