A chelating ion exchanger has been synthesized in which an o-hydroxypropiophenoneoxime group is attached chemically to the benzene ring of a divinylbenzene resin. On a short column of such resin, copper(II) is selectively adsorbed from pH 3.5 acetate solution or from pH 5 tartrate solution and can be subsequently eluted sharply by 0.1 M hydrochloric acid. Molybdenum(VI) is sorbed selectively from 0.1 N sulfuric acid solution and is eluted in a narrow band by aqueous sodium hydroxide. Numerous rapid column-chromatographic separations are reported using the resin, including some used in the analysis of NBS standard samples. 6 figures, 2 tables.
