摘要

研究了水溶液中的 I2、I- 和 [UO2(CO3)3]4- 在静态条件下在来自 Kampanovskoye 矿床的高岭土以及来自第 10 Khutor 和 Dinozavrovoe 矿床的膨润土的含金属粘土粉末上的定位过程。研究使用 2 M 水合肼溶液处理含铜、镍、锌和铁的粘土粉末。结果表明，在静态条件下，[UO2(CO3)3]4- 复合物不会从水溶液中吸附到合成粘土材料上。研究证实，合成粘土材料不仅能减少水溶液中碘分子形式的含量，还能吸附 KI 水溶液中离子形式的碘，当 I- 的浓度低于 10-2 M 时，吸附率几乎达到 100%。

Localization of Iodine and Uranyl Carbonate Complex on Metal-Containing Clay Materials from Aqueous Media

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.
