Adsorption of Uranium by Fly Ash
The effect of pH,time and different initial concentration were examined to study the properties of sorption of uranium by fly ash.The isotherm was drawn and in accordance with Langmuir and Freundlich adsorption model.Results showed that pH value was the major factor of dominating adsorption rate.The highest adsorption capacity was obtained when pH value was about 5 and time was 60min.Quantity of adsorption was increased along with increased concentration of initial uranium solution.The experiment can provide guidance for design of contaminated groundwater remediation especially fly ash zeolites treatment wall process to remediate groundwater with radiocontamination.
