Abstract:
(EN) Provided are: a silicotitanate molded body which has high strength and generates little fine powder; a method for producing this silicotitanate molded body; an adsorbent which contains this silicotitanate molded body; and a decontamination method for radioactive cesium and/or radioactive strontium, which uses this adsorbent. A silicotitanate molded body that is characterized by containing crystalline silicotitanate particles which have a particle size distribution wherein 90% or more of particles on a volume basis have a particle diameter within the range of from 1 μm to 10 μm (inclusive), and which are represented by general formula A2Ti2O3(SiO4)·nH2O (wherein A represents one or two alkali metal elements selected from among Na and K; and n represents a number of 0-2), and an oxide of one or more elements that are selected from the group consisting of aluminum, zirconium, iron and cerium.
(FR) L'invention fournit un corps moulé de silicotitanate d'une grande résistance et peu susceptible de générer une fine poudre, un procédé de fabrication de ce corps moulé de silicotitanate, un agent d'absorption contenant ce corps moulé de silicotitanate, et un procédé de traitement de décontamination de césium radioactif et/ou strontium radioactif mettant en œuvre cet agent d'absorption. Plus précisément, l'invention concerne un corps moulé de silicotitanate qui est caractéristique en ce qu'il comprend : des particules de silicotitanate cristallin représentées par la formule générale A2Ti23(SiO4)・nH2O (Dans la formule, A représente une ou deux sortes d'élément métal alcalin choisie parmi Na et K, et n représente un nombre de 0 à 2.) qui présentent une distribution granulométrique telle que sur la base du volume le diamètre de 90% des particules ou plus est supérieur ou égal à 1μm et inférieur ou égal à 10μm; et un oxyde d'au moins une sorte d'élément choisi dans un groupe constitué d'un aluminium, d'un zirconium, d'un fer et d'un cérium.
(JA) 強度が大きく、微粉の発生が少ないシリコチタネート成形体及びその製造方法、当該シリコチタネート成形体を含む吸着剤、並びに当該吸着剤を用いる放射性セシウム及び/又は放射性ストロンチウムの除染処理方法を提供する。 体積基準で90%以上の粒子の粒径が1μm以上10μm以下の範囲である粒度分布を有する、一般式:A2Ti23(SiO4)・nH2O(式中、Aは、Na及びKから選ばれる1種又は2種のアルカリ金属元素を示す。nは0~2の数を示す。)で表される結晶性シリコチタネート粒子と、アルミニウム、ジルコニウム、鉄、及びセリウムからなる群より選ばれる1種以上の元素の酸化物と、を含有することを特徴とする、シリコチタネート成形体。
