To tackle such accidents, many technologies have been developed to remove radioactive <br>cesium from water. However, the technology to decontaminate the sludge is much less advanced than that for <br>water. Thus, we focus on the decomposition of organic matter by H2O2 for decontaminating the sludge. The <br>maximum decontamination of the sea sludge by H2O2 was found to be 2.6 times higher than that by water alone, <br>and the greatest decontamination was obtained using 34.5% H2O2. We believe the extent of decontamination <br>increased for this solution because the solution pH was near the pHpzc, which would suppress the ability of the <br>sludge to absorb Cs ions. We also examined the effect of time on the decontamination of the sea sludge; <br>however, only a small increase in decontamination (1.7 times the initial value) was observed.</p>}, number={15}, journal={GEOMATE Journal}, author={Hirosuke Hirano and Takeshi Toyama and Nobuyuki Nishimiya and Kyoichi Okamoto}, year={2021}, month={Nov.}, pages={1203–1206} }
