Abstract

Effective extraction of radioactive cesium from the polluted soil into water was achieved by using the detergent composed of an acid, an alkaline metal or alkaline earth metal chloride, and a cellulose dispersant. In particular, the detergent solution consisting of 5% sulfuric acid, 20% magnesium chloride, and 1% hydroxyethyl cellulose showed high extraction ability towards radioactive cesium in polluted soil. By washing the polluted soil twice with this detergent solution, 96% of the radioactive cesium was extracted from the soil.
