Title: Surface-functionalized polyolefin fibers and their use in methods for extracting metal ions from liquid solutions

Abstract

A fiber useful in the absorption of metal ions from aqueous solutions, the fiber comprising a polyolefin backbone having a diameter of at least 1 micron and having covalently appended on its surface halogen atoms and vinyl-addition polymeric grafts functionalized with metal-binding groups, such as at least one functional group selected from carboxylate, keto, aldo, amino, imino, nitrile, amido, oxime, amidoxime, imide dioxime, and hydroxamate groups. The vinyl-addition polymeric grafts may also be further functionalized with hydrophilic groups different from the metal-binding groups, wherein the hydrophilic groups may be selected from carboxylate, sulfone, sulfonate, phosphonate, alkylammonium, iminium, amide, pyrrolidone, and polyalkyleneglycol groups. Also described are methods for producing the functionalized fibers, and methods for using the functionalized fiber, particularly in extracting metal ions from metal-containing solutions.

Method for liquid chromatographic extraction of strontium from acid solutions

Patent Horwitz, E Philip [Naperville, IL]; Dietz, Mark L [Evanston, IL]

A method and apparatus for extracting strontium and technetium values from biological, industrial and environmental sample solutions using a chromatographic column is described. An extractant medium for the column is prepared by generating a solution of a diluent containing a Crown ether and dispersing the solution on a resin substrate material. The sample solution is highly acidic and is introduced directed to the chromatographic column and strontium or technetium is eluted using deionized water.
