The Removal of Uranium and Thorium from Aqueous Solutions Onto by-pass Cement Dust (BCD)

The Removal of Uranium and Thorium from Aqueous Solutions Onto by-pass Cement Dust (BCD)

The adsorption behavior of uranium and thorium from aqueous solutions by By-pass cement dust (BCD) has been investigated by a batch technique. The uranium and thorium adsorption on BCD was studied as a function of initial concentration, weight of BCD, pH, shaking time and temperature. The uptake of...
