title: Application of xylenol orange to the separation of metal ions on amberlyst A-26 macroreticular anion-exchange resin.
abstract: The possibility of using a sulphonated aromatic organic complexing agent-Xylenol Orange-for separation of metal ions on the macroreticular anion-exchanger Amberlyst A-26 has been investigated. The dependence of retention on pH was determined by the batch method for Al(3+), Cr(3+), Mn(3+), Fe(3+), Co(2+), Ni(2+), Cu(2+), Zn(2+), Ga(3+), Rh(3+) Cd(2+), In(3+), Ir(3+), and Pb(2+). The selectivity differences make possible the separation of some of these metal ions. The following mixtures, of practical importance, have been separated: Al(3+)-In(3+), Ga(3+)-In(3+) Zn(2+)-In(3+), Cu(2+)-Mn(2+), in various ratios. The method has been applied to analysis of Ga-In alloy.
