Synthesis of Titanosilicate Sorbents and Testing of Their Sorption Properties Towards Cesium From Model Solutions of Complex Chemical Composition
Year: 2024
Type: article
Abstract: The article presents data on the sorption properties of titanosilicate sorbents synthesized at the Nanomaterial Research Centre of the FRC “Kola Science Centre of the Russian Academy of Sciences” on the basis of available titanium-containing raw materials of the Kola Peninsula. Experimental confirmation of the possibility of sorption of Cs+ cations using synthetic analogues of the minerals ivanyukite, sitinakite and zorite from a solution of a complex chemical composition simulating the solute part of accumulated highly active waste is given. Low values of Kd (mL/g) were established for the studied sorbents under conditions of high salt background in Na+ and NO3-, which significantly complicates their real practical application without modification of the initial sorption properties.
