SILICO-TITANATE MOLDED BODY AND METHOD OF PRODUCING THE SAME, CESIUM OR STRONTIUM ADSORBENT COMPRISING SILICO-TITANATE MOLDED BODY, AND METHOD OF DECONTAMINATING RADIO ACTIVE EFFLUENT USING THE ADSORBENT
To provide a silico-titanate molded body of high strength that hardly generates fine powder, a method of producing the same, and a method of decontaminating cesium or strontium using the silico-titanate molded body.SOLUTION: The silico-titanate molded body is characterized by comprising crystalline silico-titanate particles of a particle size distribution in which not less than 90% of particles on a volume basis is present in a particle size range of from 1 μm to 10 μm, represented by a general formula: ATiO(SiO)-nHO (in the formula, A represents one or two species of alkali metal elements selected from Na and K, and n represents a number of 0 to 2), and an oxide of at least one species of element selected from the group consisting of aluminum, zirconium, iron, and cerium.SELECTED DRAWING: None
【課題】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、並びに当該シリコチタネート成形体を使用したセシウム又はストロンチウムの除染処理方法を提供する。【解決手段】体積基準で９０％以上の粒子が粒径１μｍ〜１０μｍの範囲に存在する粒度分布を有する、一般式：Ａ２Ｔｉ２Ｏ３（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。【選択図】なし
