Abstract

A rapid radiochemical procedure for the separation of iodine has been devised, which is characterized by extremely high decontamination factors so as to give pure128I spectra with biological materials containing large concentrations of interferring elements such as sodium, bromine and chlorine. The method is based on ignition in oxygen followed by an oxidation-reduction and extraction-stripping cycle involving nitrite, sulfite and carbon tetrachloride. Results are presented for ten NBS and IAEA reference materials, frequently referred to in the literature.
