Removal of a mixture of Cs, Sr and Co cations from an aqueous solution using composite sorbents based on natural and synthetic zeolites

The possibility of using composite sorbents based on natural and synthetic zeolites in relation to a mixture of cations (cesium, strontium and cobalt) was studied as a result of the conducted research. The most effective was the use of a composite sorbent (clinoptilolite—50%: zeolite NaX—50%). This composite sorbent showed high sorption capacity: the sorption of cesium was 80.0%, strontium was 70.3%, cobalt was 78.6%. The technique was developed based on the PIXE (Proton Induced X-ray Emission) method and allowed for a qualitative and quantitative assessment of the content of cations.
