Separation of lead-203 from cyclotron-bombarded thallium targets by ion-exchange chromatography.

Talanta

van der Walt TN, Strelow FW, Haasbroek FJ.
PMID: 18963189
Talanta. 1982 Jul;29(7):583-7. doi: 10.1016/0039-9140(82)80006-4.

A simple method is presented for the separation of lead-203 from copper-backed thallium cyclotron targets. The procedure involves cation-exchange chromatography in hydrochloric acid and hydrochloric acid-acetone mixtures. Further purification involves anion-exchange chromatography in nitric acid-hydrobromic acid mixtures. A cation-exchange...
