CESIUM-137 ANALYSIS OF SEAWATER: ZIRCONIUM PHOSPHATE REMOVAL OF POTASSIUM-40,

Abstract

Cs137 and some of the interfering K40 and Rb87 are concentrated from seawater by coprecipitation with ammonium molybdophosphate. K40 and Rb87 are separated from the Cs137 by column chromatography. In these separations zirconium phosphate is used as an ion exchanger for K40 prior to the separation of the Rb87 on Bio-Rex 40. After purification the cesium is mounted for counting as the permanganate and its chemical recovery determined by flame photometry. (Author)
