Abstract
The extraction of the tricarbonate complex of uranyl [UO2(CO3)3]4– from aqueous solutions on clay powders from kaolin clays of the Kampanovskoye deposit and from bentonite clays of the 10th Khutor and Dinozavrovoe deposits, as well as their mixtures, was investigated. The studies were carried out with clay powders, both untreated and treated with water, 0.5 M Na2CO3 and NaNO3 solutions, and 2 M NaOH solutions. It was shown that the [UO2(CO3)3]4– complex is not sorbed on clay materials from aqueous solutions under static conditions. The filtration of an aqueous solution of [UO2(CO3)3]4– through columns with clay mixtures was established to enable the extraction up to 87% of uranium from the amount passed through the column.
