چکیده انگلیسی
An extraction chromatographic resin material containing Aliquat 336 as the liquid anion exchanger extractant and Chromosorb W as the solid support was prepared and tested for the uptake of UO22+, Np4+, Pu4+, and Pu3+ from nitric acid feed solutions. The resin beads were characterized by thermogravimetry/differential thermogravimetry (TG/DTG) and scanning electron microscopy (SEM) surface morphology analysis. The uptake trend for the metal ions from 3â¯M HNO3 was found to be Pu4+ >> Np4+ >> UO22+ > Pu3+ which clearly followed the trend of their ionic potentials. In view of the significant difference in the uptake of Np4+ with respect to those of UO22+ and Pu3+, a separation scheme was developed for the selective separation of Np from feeds containing U, Np and Pu in nitric acid. The purity of the product was verified by alpha spectrometry.
