title: Polystyrenes impregnated with ethers-A polymeric reagent selective for gold.
abstract: A polymeric reagent selective for gold was obtained by impregnating XAD-2 polymeric absorbant with ethylene diglycol dibutyl ether, a gold-selective liquid. The reagent showed a high selectivity for gold over the platinum group metals, nickel(II) and copper(II), but the selectivity relative to iron(III) was pH-dependent.
