Chemical Behavior of Carrier Free Iodine Produced by Beta-Decay and Effects of Iodine Carriers

Abstract

The effect of carriers on the chemical behavior of ¹³¹I produced from the ¹³⁰Te(n, r)¹³¹Te→^β-131I processes was investigated with paper electrophoresis, autoradiography and r-ray spectrometry.
If no carrier was added, the chromatograms of the iodine species revealed significant deposits of an unexpected chemical species between the spots of the iodide and iodate species. The addition of either iodate or periodate as carrier converted the species into iodate in the former case, and into iodate and periodate in the latter.
Referring to the already known exchange reactions between different iodine species, hence was concluded that the species observed in the experiment without carrier was the iodite species (IO^-₂), as surmised by previous authors.
