Reduction in Weight of Rice Hull Charcoal with Adsorbed Cesium and Strontium <i>Transactions of the Materials Research Society of Japan</i>

Abstract

The reduction in weight of rice hull charcoal with adsorbed cesium and strontium was examined in this study. It was carefully examined whether the adsorbed cesium and strontium volatilized during the weight loss process. By heating the charcoal that had adsorbed cesium and strontium to 400 °C in air, we achieved a weight reduction of approximately 28%. The amount of cesium and strontium present in the gas that volatilized during heating was quantified. The value obtained was below the detection limit of the atomic absorption spectrometer. From the obtained results, it was found that rice hull charcoal with adsorbed cesium and strontium can undergo weight reduction on being heated, without volatilizing the adsorbed metal.
