<p><P>PROBLEM TO BE SOLVED: To provide a method for producing an adsorbent that can economically and efficiently compose an adsorbent with extremely excellent characteristics of adsorbing and removing cesium, strontium, etc., and a hybrid type adsorbent produced by the method. <P>SOLUTION: The method for producing the adsorbent includes mixing calcium oxide, silicon dioxide, and aluminum oxide to prepare raw material powder so that an Al/(Al+Si) molar ratio is within a range of 0.03 or more and 0.25 or less and that a Ca/(Al+Si) molar ratio is within a range of 0.50 or more and 0.83 or less, adding a sodium hydroxide or potassium hydroxide aqueous solution to the raw material powder to obtain an alkaline condition, and then performing hydrothermal synthesis treatment. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
