REMOVAL METHOD OF CESIUM AND STRONTIUM IN HIGH CONCENTRATION CONTAMINATED WATER

摘要

PROBLEM TO BE SOLVED: To provide a removal method of radioactive cesium and radioactive strontium in high concentration contaminated water.;SOLUTION: Aqueous silicic acid solution formed by synthesis by electrolysis is mixed to radioactive cesium included in solution and to radioactive strontium solution, and further alkali is added for coagulation settling. A deposition matter obtained by filtration is solidified and removed by drying or sun drying. The radioactive cesium and the radioactive strontium accumulated in soil or burned ash are washed with water for making them into solution and they can be removed as the solution, similarly.;COPYRIGHT: (C)2015,JPO&INPIT
