Description

The material for removing, recovering and fixing of the cesium etc. which were emitted by the accident of the Fukushima Daiichi nuclear power plant into environment is needed. Authors' research group has developed a new cesium adsorption and fixation material based on an autoclaved lightweight concrete (ALC) that consists of tobermorite. High cesium removal performance is revealed by hydrothermal treatment of a tobermorite with sodium hydroxide. In this paper, cesium and strontium removal performance of the powder and the bulk of this NaOH treated ALC sample and the removal performance of cesium and strontium from the sea water by these samples are explained.

Abstract (Japanese)

福島第一原子力発電所の事故により環境中に放出されたセシウム等の除去,回収,および固定化に向けた材料が必要とされている。著者らの研究グループでは,トバモライトが主成分である軽量気泡コンクリートを基材としたセシウム吸着・固定化材料を開発してきた。トバモライトを水酸化ナトリウムで処理することで,高いセシウム除去性能が発現する。ここでは,この試料の粉末とバルク体でのセシウム・ストロンチウム除去性能,およびそれらを用いた海水中からのセシウム・ストロンチウムの除去性能について解説する。(著者)
