Description
Adsorption of gadolinium on activated charcoal has been studied as a function of shaking time, pH, contrentation of adsorbate and temperature. Gadolinium adsorption obeys the Langmuir isotherm. Δ Ho and Δ So were calculated from the slope and intercept of the ln KD 1/T plot. The influence of different cations and anions on gadolinium adsorption has been examined. The adsorption of other metal ions on activated charcoal has been studied under optimum conditions to check the selectivity of gadolinium adsorption. Consequently, gadolinium was removed from Ni, V, Zn, Cu, Rb, Sr and Mn. More than 97% of the adsorbed gadolinium on activated charcoal can be recovered with 35 ml of 3M HNO3 solution. Wavelength dispersive X-ray fluorescence spectrometer was used for measuring gadolinium concentration. (author) 14 refs.; 12 figs.; 2 tabs
