It was found that the electrophoresis on paper ensures a better separation of active contaminants than paper chromatography. Using the acid electrolytes, perchloric or nitric acid, an absolute separation of orthophosphate, sulfate, and chloride was achieved, i.e., of ionic forms, in which the impurities of radioisotopes S/sup 35/, Cl/sup 36/, and of irradiated chlorides as a result of production processes are present. Trace amounts of sulfates were separated from phosphates using diluted hydrochloric acid as electrolyte. The separation of radiotellurium from radioiodine was achieved only after the oxidation of samples using different electrolytes at the plus and minus electrode. Using the results of Zimakov et al., contaminating ruthenium from Sr and Y in 2% solution of potassium ferrocyanide and contaminating radiocesium from Sr/sup 90/ in 0.5 N sodium hydroxide were separated by means of paper electrophoresis.
