Title (EN) ADSORBENT AND METHOD FOR PRODUCING SAME
(FR) ADSORBANT ET SON PROCÉDÉ DE PRODUCTION
(JA) 吸着剤及びその製造方法
Abstract:
(EN) The purpose of the present invention is to provide an adsorbent which is not susceptible to the effects of calcium and which can selectively adsorb and remove strontium contained in water. Provided is a strontium adsorbent which contains barium silicate. The barium silicate may be amorphous or crystalline. The BET specific surface area of the adsorbent is 15-50 m2/g. The BaO/SiO2 molar ratio in the adsorbent is preferably 0.6-0.7. In addition, the adsorbent preferably contains the BaO component at a proportion of 50 mass % or higher.
(FR) La présente invention vise à fournir un adsorbant qui est difficilement affecté par le calcium et qui peut adsorber et éliminer sélectivement le strontium contenu dans l'eau. L'invention concerne un adsorbant de strontium qui contient du silicate de baryum. Le silicate de baryum peut être amorphe ou cristallin. La surface spécifique BET de l'adsorbant est de 15-50 m2/g. Le rapport molaire BaO/SiO2 dans l'adsorbant est de préférence 0,6-0,7. En outre, l'adsorbant contient de préférence un constituant de BaO à une proportion de 50 % en masse ou plus.
(JA)  カルシウムの影響をほとんど受けずに、水中に含まれるストロンチウムを選択的に吸着除去できる吸着剤を提供すること。ケイ酸バリウムを含む、ストロンチウムの吸着剤である。ケイ酸バリウムは非晶質のものであるか、又は結晶質のものである。吸着剤はそのBET比表面積が15m/g以上50m/g以下である。吸着剤は、BaO/SiOのモル比が0.6以上0.7以下であることが好適である。また吸着剤は、BaO成分を50質量%以上の割合で含有することも好適である。
