Title: Valery Radchenko: Innovator in Radioactive Ion Chelation
Introduction
Valery Radchenko is a notable inventor based in Los Alamos, NM (US). He has made significant contributions to the field of radioactive ion chelation, holding 2 patents that showcase his innovative approaches to complex chemical processes.
Latest Patents
Radchenko's latest patents include the development of nitrogen-rich macrocyclic ligands and chelation complexes for the selective chelation of radioactive bismuth ions. This process involves exposing a ligand to an aqueous solution containing both bismuth and actinium radionuclide ions. Under specific conditions, the bismuth ions selectively chelate to the ligand, forming cationic complexes that can be separated from actinium ions. The ligands are designed with a structure based on a 12-membered cyclen ring and may include functional groups that can be modified for targeted alpha therapy.
Another significant patent involves the separation of protactinium, actinium, and other radionuclides from proton-irradiated thorium targets. In this process, the thorium target is dissolved in concentrated HCl, which forms anionic complexes of protactinium. This allows for the effective separation of protactinium from thorium and other radionuclides using a column of strongly basic anion exchanger resin.
