Determination of Cs-137 in environmental water by ion-exchange chromatography

Gaur, Sushma ;
  • 초록  

    Abstract Methods of Cs-137 determination employing ion-exchange concentration in environmental waters such as seawater and river water have been reviewed. Ammonium molybdophosphate (AMP) is the most used inorganic ion exchanger for the determination of cesium in water. Since AMP could be obtained only in the form of fine crystals, it was difficult to use it in the columns for separation and concentration of Cs-137. Columns with favorable flow-rates, however, could be prepared by precipitating AMP into a resinous structure. Another inorganic ion exchanger, potassium cobalt ferrocyanide (KCFC), was also successfully used for rapid, selective and quantitative concentration of radioactive cesium from neutral, acidic and basic solutions. AMP, KCFC and copper hexacyanoferrate(II) precipitated on silica granules and anion-exchange resins were found superior for concentration of Cs-137 by column method. Recent developments in analytical technology such as application of ion chromatography in the determination of Cs-137 seems promising. Cyclic voltammetry using a NiFe(CN) 6 2− derivatized nickel working electrode may be used for the determination of total concentration of cesium in surface waters.
