Abstract: A polyfunctional amine, such as cyclam, substituted with 4-(N,N-dimethylao) benzonitrile, exhibits triple fluorescence and complexes with metal ions. The complexation of metal ions with the fluorophore changes the triple fluorescence characteristics of the fluorophore. Thus, this substituted polyfunctional amine provides an effective indicator for the qualitative and quantitative detection of metals.

Abstract: A method for removing, separating, and concentrating certain selected ions from a source solution that may contain larger concentrations of other ions comprises bringing the source solution in contact with a composition comprising an ion-binding ligand covalently bonded to a membrane having hydrophilic surface properties. The ligand portion of the composition has affinity for and forms a complex with the selected ions, thereby removing them from the source solution. The selected ions are then removed from the composition through contact with a much smaller volume of a receiving solution in which the selected ions are either soluble or which has greater affinity for the selected ions than does the ligand portion of the composition, thereby quantitatively stripping the complexed ions from the ligand and recovering them in concentrated form in the receiving solution. The concentrated ions thus removed may be further separated and recovered by known methods. The process is useful in the removal of selected ions, including noble metals and other transition metals from a variety of source solutions such as are encountered in semiconductor, nuclear waste cleanup, metals refining, environmental cleanup, providing ultra high purity fluids, electric power, and other industrial enterprises. The invention is also drawn to the ligand-membrane compositions.

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.
