PREPARATION AND CHROMATOGRAPHIC APPLICATIONS OF AN AMIDE RESIN

Synthetic routes are discussed for incorporation of a tertiary aliphatic amide group in a macroporous polystyrene-di-vinyibenzene resin. The amide resin retains uranium(VI), thorium(IV), and zirconium(IV) selectively from aqueous solution, pH 3.0. A liquid chromatographic separation scheme using the resin is given and quantitative results are obtained for uranium in synthetic and actual samples, and for thorium in synthetic samples. Gold(III) and palladium(II) are selectively retained by the resin from aqueous solutions containing hydrochloric acid. The resin has a capacity for gold of 1.7 mmol/g. © 1978, American Chemical Society. All rights reserved.
