Abstract
The processes of localization of I2, I–, and [UO2(CO3)3]4– from aqueous solutions under static conditions on metal-containing clay powders from kaolin clays of the Kampanovskoye deposit and from bentonite clays of the 10th Khutor and Dinozavrovoe deposits were investigated. The studies were carried out with Cu-, Ni-, Zn-, and Fe-containing clay powders treated with a 2 M hydrazine hydrate solution. It was shown that the [UO2(CO3)3]4– complex is not sorbed on the synthesized clay materials from aqueous solutions under static conditions. It was established that the synthesized clay materials are capable of not only reducing the amount of the molecular form of iodine in an aqueous solution, but also sorbing the ionic form of iodine from an aqueous solution of KI to almost 100% at a concentration of I– less than 10–2 M.
