Uranium capture from aqueous solution using cement kiln dust; equilibrium and kinetic studies

Abstract

Contamination of aquatic ecosystems with radioactive nuclides is significantly threaten the human body. So, finding effective and economical sorbents is significant for uranium elimination from an aqueous solution is important. In this study, Cement kiln dust (CKD) is a solid waste produced during the cement production process was utilized as sorbent for the uranium sorption from an aqueous solution. The maximum adsorption of 156.2 mg g−1 at pH 3.0 which reflects good sorption properties for the CKD. All in all, the displayed data declares that the CKD material possess an extraordinary tendency for U(VI) recovery from aquatic environments.
