The behaviour of I-, IO3- and IO4- in silica gel thin layer chromatography and their separation with ammonia-alcohol eluents (saturated open-chain C1 to C5 alcohols being used) have been studied with the help of radioisotopes. Changes in RF values of the studied anions caused by changes of the alcohol, ratio of the organic to aqueous phase in the mixture, and overall analytical concentration of ammonium ions have been determined. Influence of alcohol on kinetics of development of the chromatograms with the alcohol-water mixtures has been determined, too.
