| 1 | An adsorption study of^99Tc using nanoscale zero-valent iron supported on D001 resin显示文摘Nanoscale zero-valent iron(nZVI)supported on D001 resin(D001-nZVI)was synthesized for adsorption of high solubility and mobility radionuclide^99Tc.Re(VII),a chemical substitute for^99Tc,was utilized in batch experiments to investigate the feasibility and adsorption mechanism toward Tc(VII).Factors(pH,resin dose)affecting Re(VII)adsorption were studied.The high adsorption efficiency of Re(VII)at pH=3 and the solid-liquid ratio of 20 g/L.X-ray diffraction patterns revealed the reduction of ReO^?4 into ReO2 immobilized in D001-nZVI.Based on the optimum conditions of Re(VII)adsorption,the removal experiments of Tc(VII)were conducted where the adsorption efficiency of Tc(VII)can reach 94%.Column experiments showed that the Thomas model gave a good fit to the adsorption process of Re(VII)and the maximum dynamic adsorption capacity was 0.2910 mg/g. | Lingxiao FU Jianhua ZU Linfeng HE Enxi GU Huan WANG | 2020 | Frontiers in Energy2020，14，1： | 1 |
