Development of 225Ac Production from Low Isotopic Dilution 229Th

“…Ac III is eluted from the BDGA in 0.05 M HNO 3 and through a prefilter resin (VIII) to remove any residual organics. Affinity constants for these resins are well reported. − Experimental details, such as the resin bed and mobile phase volumes, can be found in the Experimental Section. The process reported herein was conducted on 229 Th cows of ∼1 μCi (37 kBq).…”

Cation-Exchange Techniques in Radiochemistry

“…Other bivalent metal ions and rare earths are quantitatively retained. Sulphosalicylate was also used by a few other workers(12,129,452, 534, 656).Suranova (575) used 4-aminosalicylic acid to separate Ga from Cd and Zn. Cation -exchange separations of the elements 6.1.…”
