Filter paper was impregnated with zirconium phosphate and zirconium tungstate, rinsed, dried, and cut into bands l2 cm long and 2 cm wide. The bands were hung in an atmosphere of water vapor at 60 deg C and scanned with a Geiger counter at regular intervals to determine the short-lived radioisotopes. The following separations were carried out: Pb/sup 211/ - Tl/sup 207/--Tl/sup 204/ (eluant HCl, time 5 min); Pb/sup 212/-Bi/ sup 212/Ba/sup 140/-La/sup 140/(eluant HCl or NH/sub 4/NO/sub 3/, time 30 min), Sr/sup 9 Y/sup 90/ (eluant HCl or NH/sub 4/NO/sub 3/, time 30 min), Ra/sup 228/ -- Ac/sup me 20 min); and monovalent from trivalent thallium allows a quantitative determination of the 2 valence states of the same element. The separation of radium and francium by a rapid method is of great importance because Fr/sup 223/ has a half-life of only 21 min. (OID)
