The leaching rate of cobalt-60 and cesium-137 in cement has been studied. The solidification matrix was a standard Portland cement mixed with 300-360 (kg/m 3) spent ion exchange resins, with or without 2-5% of bentonite clay. The leaching rates from the cement marix were measured as Co-60: (4, 2-6,
Studies have been carried out on the immobilization of spent ion-exchange resins produced in nuclear power plants in urea-formaldehyde matrix. The matrices were prepared by incorporating different types of ion-exchange resins in the pH range of 4.5 to 5.0, using boric acid as a catalyst. Characteriz
