Abstract
A comparative study was conducted on the adsorptions of cobalt(II) and nickel(II) from aqueous ammonium nitrate solutions on a Levextrel resin containing acidic organophosphinate extractant, Cyanex 272, as an active component and on chelating resins containing phosphorus-based acidic functional groups. It was found that the Levextrel resin has much higher selectivity for cobalt(II) over nickel(II) then the chelating resins. The origins of the low selectivity of the chelating resins are qualitatively discussed.Keywords
