Abstract

The synthesis of a poly(hydroxamic acid) ion exchange resin from cross-linked poly-(acrylonitrile) is described. This ion exchanger is highly selective for vanadium, iron and mercury; its fast equilibration rate makes it suitable for column work. Curves showing the dependence of the total capacity against pH are presented for nine metal species. This ion exchanger is more stable to loading - acid washing cycles than the hydroxamic acid resins reported previously.
