摘要

介绍了8种n -苯基取代聚丙烯酸羟肟酸作为离子交换树脂的制备及其性能。在醚介质中，聚丙烯酰氯与n -芳基羟胺反应合成了这些化合物。测定了两种树脂的螯合性能，并进行了比较。研究了二价金属离子的萃取随pH的变化规律及其吸附动力学。本文还叙述了从混合物中分离金属离子的色谱方法。

Polyhydroxamic acids: synthesis, ion exchange separation and atomic absorption spectrophotometric determination of divalent metal ions

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.
