... On the other hand, iron even at low concentration (10-4 mol/l) affects significantly the lanthanide recovery and leads to almost 45% separation recovery at [Fe3+]= 0.01 mol/l (Fig. 4). The effect is attributed to the higher affinity of the resin for the Fe3+ cations under the given conditions (pH 2. ...
