Synthesis and metal binding properties of poly(hydroxamic acid) resins from poly(ethyl acrylate-co-divinylbenzene) beads

Poly(hydroxamic acid) resins from crosslinked poly(ethyl acrylate)s were prepared and their metal binding properties were investigated. The metal binding capacities of this type resin for metal ions were determined at specific pH. In the acidic region, the chelating resin showed high adsorption capacity for copper, iron, vanadium, and uranium. Metal adsorption capacities varied according to polymerization condition, i.e. crosslinking ratio and degree of dilution. Equilibration rates of the chelating resins were investigated to evaluate their use as materials for chromatographic separation. Selectivity for various metals was also observed from the mixed metal solution. © 1995 John Wiley & Sons, Inc.
