Effect of Competing Ions on Multisorption (Cs+, Sr2+) by Composite Sorbents Based on Natural and Synthetic Zeolites
Abstract
In the course of the research, the effect of competing ions (Na+) on multisorption (Cs+, Sr2+) by composite sorbents based on natural and synthetic zeolites under static conditions was studied. It was found that the maximum concentration of competing ions (0.4 g of NaCl per 100 ml of solution) leads to a decrease in cesium sorption by 20%, and strontium sorption decreases by 10%. At the same time, high rates of sorption of cesium and strontium are preserved. Thus, for a composite sorbent (clinoptilolite -30%: zeolite NaX -70%), the sorption of cesium was 67.9%, and the sorption of strontium was 87.6%. The analytical technique was developed on the basis of the PIXE (Proton Induced X-ray Emission) method and made it possible to qualitatively and quantitatively determine the content of isotopes. The work was performed at the analytical nuclear-physical complex "Sokil". The energy range of the electrostatic accelerator is 200-2000 keV. The complex made it possible to carry out all the main methods of analysis using ion beams. The targets were placed in the exit, at the Chamber for PIXE. To carry out measurements, a vacuum with a pressure of 10-4 Pa was created in the chamber. To excite the atoms of cesium, strontium, a proton beam with an energy of Ер≈1400 keV was used. The characteristic X-ray radiation of the L-series of cesium atoms and K-series of strontium atoms was recorded by two detectors: XR-100CR Si-PIN X-Ray and Ge(HP). The sorption coefficient (Sorption, %) was used as a quantitative characteristic of the interaction of sorbents with cesium, strontium.
