Novel ion exchange chromatography method for nca arsenic separation.


PMID 28130978

Abstract

A high-performance liquid chromatography (HPLC) device equipped with an anion exchange column was used to isolate nca (77)As from reactor irradiated (nat)GeO2 targets. The oxidation states of the isotope (77)As during the process was verified by thin layer chromatography. The radionuclidic purity of the separated fractions was checked by gamma measurements and it was found to be 99.91% for the As fraction. The elaborated method was applied to separate the isotope (74)As from cyclotron irradiated (nat)GeO2 targets too.
