• Note (General): THE PRESENT STUDY HAVE BEEN CARRIED OUT TO ESTABLISH THE FINAL DISPOSAL METHODS FORTHE WASTES CONTAINING RADIOACTIVE IODINES. FROM THE PREVIOUS STUDIES,IT WAS CLARIFIEDTHAT THE IODINE SPECIES EXIST AS I-IONS IN THE GROUND WATER AND THAT ANIONS SUCH AS I-IONS ARE LITTLE ADSORBED ON THE NATURAL MINERALS. HENCE,THREE KINDS OF ADSORBENTS,I.E.,CINNABAR,MONTMORILLONITES CONTAINING AG-THIOUREA COMPLEX,AND INORGANIC ION EXCHANGERS,WERE EXAMINED AS THE ARTIFICIAL BARRIER MATERIALS. FURTHERMORE,THE HYDROHORBIC IODINE ADSORBENTS WERE STUDIED FROM THE VIEWPOINT OF LEACHING-RESISTANT. THE RESULTS ARE SUMMARIZED AS FOLLOWS:1.ADSORPTION MECHANISM OF CINNABAR1.THE ADSORPTION OF I-IONS ON THE CINNABAR WAS NOT AFFECTED BY AN INCREASE INTEMPERATURE AND THE COEXISTENT IONS. THESE RESULTS SUGGEST THAT THE ADSORPTION OF I-IONS ON CINNABAR TAKES PLACE THROUGH MECHANISM EXCEPT FOR THE ION EXCHANGE.2.THE AMOUNT OF I-IONS ADSORBED ON THE CINNABAR WAS FOUND TO BE AROUND 10-5MOL/G,WHICH IS EXTREMELY SMALLER THAN; None
