Abstract
The adsorption of cerium on activated charcoal has been studied as a f unction of shaking time, pH, concentration of adsorbate and temperatur e. The adsorption of cerium obeys Freundlich and Langmuir isotherms. T he influence of different cations and anions on cerium adsorption has been examined. The adsorption of other metal ions on activated charcoa l has been studied under specified conditions to check its selectivity for cerium adsorption. Consequently, cerium was removed from a mixtur e containing Ce, Ba, Sr, Ru, Cs, Cr, Nd, Pr and In. About 99% of the a dsorbed cerium on activated charcoal can be recovered with 3M HNO3 sol ution. A wavelength dispersive X-ray fluorescence spectrometer was use d for measuring the cerium concentration.
