    Abstract: Compositions and methods for selectively binding metal ions from source solutions are disclosed. The composition is comprised of a polyamide-containing ligand covalently bonded to a particulate solid support through a hydrophilic spacer having the formula SS—A—X—L. In this formula, SS is a particulate solid support such as silica or a polymeric bead, A is a covalent linkage mechanism, X is a hydrophilic spacer grouping, and L is a polyamide-containing ligand having three or more amide groups and two or more amine nitrogens separated by at least two carbons with the proviso that when SS is a particulate organic polymer, A—X may be combined as a single covalent linkage. The separation is accomplished by passing a source solution containing the ions to be separated through a column containing the particulate composition, causing the selected ions to be complexed to the polyamide-containing ligands, and subsequently removing the selected ions from the column by passing an aqueous receiving solution through the column and quantitatively stripping the selected ions from the polyamide-containing ligand.

    Abstract: The invention recognizes the deleterious effects of trace, and even undetectable amounts of multivalent cations on the separation of mixtures of polynucleotides, especially double stranded polynucleotides, and provides an improved method for separating such mixtures on wide pore, non-polar separation media by eliminating multivalent cations from the all aspects of the separation process. This is accomplished by using components in the separation process which are materials which do not release metal cations. In addition, the use of cation capture resins and other methods to remove residual traces of multivalent cations from eluting solvents, sample solutions, separation media, and system components is described. It is also important to remove any traces or organic contaminants from solvents solutions and system parts. Taking similar steps to remove residual traces of multivalent cations and organic impurities from the separation process, the invention may also be used in a batch process to separate mixtures of polynucleotide fragments.

    Abstract: A solid material for recovering metal ions from aqueous streams, and methods of making and using the solid material, are disclosed. The solid material is made by covalently bonding a chelating agent to a silica-based solid, or in-situ condensing ceramic precursors along with the chelating agent to accomplish the covalent bonding. The chelating agent preferably comprises a oxime type chelating head, preferably a salicylaldoxime-type molecule, with an organic tail covalently bonded to the head. The hydrocarbon tail includes a carbon-carbon double bond, which is instrumental in the step of covalently bonding the tail to the silica-based solid or the in-situ condensation. The invented solid material may be contacted directly with aqueous streams containing metal ions, and is selective to ions such as copper (II) even in the presence of such ions as iron (III) and other materials that are present in earthen materials. The solid material with high selectivity to copper may be used to recover copper from mining and plating industry streams, to replace the costly and toxic solvent extraction steps of conventional copper processing.

    Abstract: Compositions and methods for selectively binding metal ions from a source solution comprise using a polyhydroxypyridinone-containing ligand covalently bonded to a particulate solid support through a hydrophilic spacer of the formula SS-A-X-L (HOPO)n where SS is a particulate solid support such as silica or a polymeric bead, A is a covalent linkage mechanism, X is a hydrophilic spacer grouping, L is a ligand carrier, HOPO is a hydroxypyridinone appropriately spaced on the ligand carrier to provide a minimum of six functional coordination metal binding sites, and n is an integer of 3 to 6 with the proviso that when SS is a particulate organic polymer, A-X may be combined as a single covalent linkage. The separation is accomplished by passing a source solution containing the ions to be separated through a column containing the particulate composition, causing the selected ions to be complexed to the HOPO ligands and subsequently removing the selected ions from the column by passing an aqueous receiving solution through the column and quantitatively stripping the selected ions from the HOPO ligand.

    Abstract: The present invention provides calixpyrrole, calixpyridinopyrrole, and calixpyridine macrocycles, having 4, 5, 6, 7, or 8 heterocyclic rings, as well as syntheses, derivatives. conjugates, multimers, and solid supports thereof. Such macrocycles have proved to be effective and selective ion- and neutral molecule-binding agents forming supramolecular ensembles, and ion- and neutral molecule-separation agents. The macrocycles are fully meso-non-hydrogen-substituted porphyrinogens, a few molecules of which were previously known but not recognized as possessing anion- or molecule-binding properties. The binding mode is noncovalent, primarily that of hydrogen-bonding, thereby providing a new mode for liquid chromatography, that of Hydrogen Bonding Liquid Chromatography. Further useful applications of the macrocycles provided herein include environmental remediation by removal of undesired ions or neutral molecules, and removal of phosphate for kidney dialysis.
