The determination of thallium with potassium chlorate is chosen as an example for the earlier suggested new radio-oxidimetric
titration procedure, in which phase separation is achieved by means of a strongly basic anion exchanger in the solution. Concentrations
of thallium down to 2·10−6M have been determined. Special care has to be taken for concentrations lower than 10−5M as UV radiation is a disturbing factor. Other oxidizing agents have also been tested.
