| Abstract | ||||
| Thorium adsorption from low concentration nitrate leach liquors was studied using glycidyl methacrylate/divinyl benzene/amine polymers. RI and RII resins were prepared by the reaction of GMA/ DVB copolymers with ethylenediamine and diethylenediamine, respectively. The thermal stability of the resins was studied thermogravimetrically. The prepared resins were applied for the adsorption of thorium from synthetic and real samples. The results indicated that; the adsorption of Th(IV) increased as the solution pH increased and the maximum metal adsorption was 50 and 64 mg/g for RI and RII, respectively. Thorium (IV) adsorbed per mass unit of RI and RII resins increased from 50 to 64 and from 66 to 88 mg/g by increasing the temperature from 293o to 323o K respectively. The obtained results indicated the applicability of RI and RII for Th(IV) adsorption. Finally, RI and RII resins were used for the separation of Th(IV) from three granite samples leach liquors. | ||||
