摘要: The adsorption of thorium on activated charcoal has been studied as a function shaking time, amount adsorbent, pH, concentration adsorbate and temperature. Adsorption obeys the Langmuir isotherm. ΔH0 ΔS0 were calculated from slope intercept ln KD vs. 1/T plots. influence different anions cations examined. other metal ions under specified conditions to check its selectivity. Consequently, was removed Cs, Co, Ba, Cr, Sr, Cd, Cu, Mn Zn. More than 98% adsorbed can be recovered with 55 ml 3M HNO3 solution. Wavelength dispersive X-rays fluorescence spectrometer used for measuring concentration.
