Abstract

PURPOSE:To obtain the adsorbent for uranium and strontium, which is easily prepared and displays stable adsorption power, cheaply by a method wherein Al2O3, activated carbon and MgO powder are heated, agitated and filtered with distilled water and dried. CONSTITUTION:Al2O3 powder in approximate 200-300 meshes for chromatograph, powdered activated carbon and MgO powder in approximate 200-300 meshes are agitated and mixed in distilled water adjusted at approximate 70-80 deg.C. The mixture is filtered, dried at approximate 110 deg.C and used as an adsorbent. The absorption power of the adsorbent of uranium and strontium in seawater is higher than conventional titanic acid adsorbents. When uranium and strontium adsorbed are heated with an alkali carbonate water solution such as sodium carbonate, etc., the uranium and the strontium are dissolved and desorbed as each carbonate, and easily recovered.
