SILICOTITANATE MOLDED BODY, METHOD FOR PRODUCING SAME, CESIUM AND/OR STRONTIUM ADSORBENT CONTAINING SILICOTITANATE MOLDED BODY, AND DECONTAMINATION METHOD FOR RADIOACTIVE WASTE LIQUID USING SAID ADSORBENT
Provided are a silicotitanate molded body having high strength and reduced generation of fine powder, a production method thereof, an adsorbent comprising the silicotitanate molded body, and a decontamination method of radioactive cesium and/or radioactive strontium by using the adsorbent.The silicotitanate molded body comprises: crystalline silicotitanate particles that have a particle size distribution in which 90% or more, on volume basis, of the particles have a particle size within a range of 1 µm or more and 10 µm or less and that are represented by a general formula of A2Ti2O3(SiO4)·nH2O wherein A represents one or two alkali metal elements selected from Na and K, and n represents a number of 0 to 2; and an oxide of one or more elements selected from the group consisting of aluminum, zirconium, iron, and cerium.
