| Abstract: | In this paper, the sorption behaviour and mechanism of uranyl ion onto the macroporous phosphonic acid resin are reported. The macroporous phosphonic acid resin has a good adsorption ability for uranyl ion in the HAc-NaAc medium at PH 3. 0. The uranyl ion adsorbed on the macroporous phosphonic acid resin can be eluted by 5% aqueous Na2CO3 quantitatively. The saturated static adsorption capacity is 450. 67 mg/g. The basic adsorption parameters and mechanism of macroporous phosphonic acid resin for uranyl ion were determined by chemical analysis and IR spectrometry. |
