Title: Diphonix: A new ion exchange resin for the treatment of industrial waste streams, contaminated groundwaters, and mixed-wastes

Abstract

The resin contains geminally substituted diphosphonic acid functional groups; it is synthesized by copolymerization of a tetralkylvinylidene diphosphonate with styrene, divinylbenzene, and acrylonitrile, followed by deesterifaction by refluxing with conc. HCl (the nitrile group is hydrolyzed to a carboxylic acid). The diphosphonic acid functional dominates the resin behavior toward metal ions; it has strong affinity for actinides in all oxidation states, even in 10 M HNO{sub 3} and high salt concentrations. (Efficient agents for stripping actinides from Diphonix all have a strong complexing agent containing the gem-diphosphonic acid functionality.) Diphonix can also remove heavy, toxi metals in high salt concentrations. 4 figs, 2 tabs.
