“…As with our data, they reported higher adsorption of Sc from nitric acid solutions than from hydrochloric acid solutions, however neither author reported a decrease in Sc adsorption from 0.1 M to 1 M HCl. Furthermore, the absorption of Sc reported in our study is higher than reported by both Alliot [16] and Dirks [15]. The reason for the difference in magnitude of Sc adsorption may be due to differences in the experimental methods used.…”

“…The reason for the difference in magnitude of Sc adsorption may be due to differences in the experimental methods used. For example, while the volumes used for the k 0 values are similar to Dirks (1.2 mL vs. 1.4 mL for Dirks), the concentration of Sc used by Dirks was much higher (0.11 ug mL -1 vs. 10 ug mL -1 used by Dirks) [15]. Furthermore, the DGA resin used by both Alliot and Dirks were obtained from TrisKem; it is uncertain whether the TrisKem DGA is identical to the Eichrom DGA.…”

A new method was developed for separating Co, Fe, and Sc from complex debris matrices using the extraction chromatography resin DGA. The activation products Co-58, Mn-54, and Sc-46 were used to characterize the separation of the synthetic melt glass solutions. In the separation scheme that was developed, Au, Co, Cu, Fe, Sc, and Ti were separated from the rest of the sample constituents. In this paper, the synthetic melt glass separation method, efficiency, recoveries, and the length of procedure will be discussed. Batch contact adsorption studies for Na and Sc for DGA resin are discussed as well.

Two macrocyclic ligands based on cyclam with trans-disposed N-methyl and N-(4-aminobenzyl) substituents as well as two methylphosphinic (H2L1) or methylphosphonic (H4L2) acid pendant arms were synthesised and investigated in solution. The ligands form stable complexes with transition metal ions. Both ligands show high thermodynamic selectivity for divalent copper over nickel(II) and zinc(II)-K(CuL) is larger than K(Ni/ZnL) by about seven orders of magnitude. Complexation is significantly faster for the phosphonate ligand H4L2, probably due to the stronger coordination ability of the more basic phosphonate groups, which efficiently bind the metal ion in an "out-of-cage" complex and thus accelerate its "in-cage" binding. The rate of Cu(II) complexation by the phosphinate ligand H2L1 is comparable to that of cyclam itself and its derivatives with non-coordinating substituents. Acid-assisted decomplexation of the copper(II) complexes is relatively fast (τ1/2 = 44 and 42 s in 1 M aq. HClO4 at 25 °C for H2L1 and H4L2, respectively). This combination of properties is convenient for selective copper removal/purification. Thus, the title ligands were employed in the preparation of ion-selective resins for radiocopper(II) separation. Glycidyl methacrylate copolymer beads were modified with the ligands through a diazotisation reaction. The separation ability of the modified polymers was tested with cold copper(II) and non-carrier-added (64)Cu in the presence of a large excess of both nickel(II) and zinc(II). The experiments exhibited high overall separation efficiency leading to 60-70% recovery of radiocopper with high selectivity over the other metal ions, which were originally present in 900-fold molar excess. The results showed that chelating resins with properly tuned selectivity of their complexing moieties can be employed for radiocopper separation.
