摘要
The preparation and properties of 8 N-phenylsubstituted polyacrylohydroxamic acids as ion exchange resins are described. These were synthesized by the reaction of polyacryloyl chloride with N-aryl hydroxylamines in etherial medium. The chelating properties of the resins were determined and compared with each other. The extraction of divalent metal ions as a function of pH and kinetics of their sorption were studied. The chromatographic separation of metal ions from the mixtures is also described.
