Abstract
Xylenol Orange was bonded on an anion-exchange resin $(Amberlite\;lRA \;400,\;in\;Cl^-\;form)$ by batch equilibration. The resin was proved to be stable in acidic solutions of about O.1 M HCl, $HNO_3\;or\;H_2SO_4$. Sorption capacities for the metal ions on the Amberlite IRA 400 bonded with xylenol orange have been measured by batch method. The result showed that Fe(lII) is higher than any other metals for sorption capacity. The preconcentration and the separation of Fe(lll) from the mixture soIution, therefore, were carried out with the O.1 M sulfosalicylic acid as an eluent.????????????6??K?޿??????��????
