A study on the adsorption properties of illite for radioactive cesium and strontium for the treatment of contaminated water in nuclear power plant

This study was conducted to confirm the Cs-137 and Sr-90 adsorption properties of illite. In the experimental method, illite was added to Cs-137 and Sr-90 solutions and stirred. And Following the completion of the adsorption reaction, the solid/liquid phase was separated using a centrifuge, and the adsorption rate was calculated by measuring the radioactivity concentration of the separated liquid phase using a gamma nuclide analyzer, Liquid Scintillation Count (LSC). As a result of the experiment, after reacting for 30 min, 94% of Cs-137 was adsorbed. And 84.26% of Sr-90 was adsorbed.

Automated summary

The study confirmed that illite has good adsorption properties for Cs-137 and Sr-90, with adsorption rates of 94% and 84.26% respectively, after a reaction time of 30 minutes.
