Description

To assess the safety for disposal of radioactive cement-waste matrix, the leaching Cs+ and Co2+, has been studied. This paper also presents results from studies made to determine the influence of bentonite and zeolite in immobilization of these metal ions. Leaching tests were carried out in accordance with a method by Hespe during 98 days. From the leaching data the apparent diffusivity of cobalt and cesium in the cement matrix was measured. (author)

Abstract (Serbian)

U cilju bezbednog odlaganja radioaktivnog otpada ispitivano je izlucivanje jona Cs+ i Co2+ iz cementnog matriksa. Ovaj rad se bavi i istrazivanjem uticaja bentonita i zeolita na proces imobilizacije ovih katjona. Ispitivanje izlucivanja jona Co2+ i Cs+ imobilisanih u cementnom matriksu vrseno je standardnom metodom po Hespeu u periodu od 98 dana. Na osnovu podataka izlucivanja izracunate su vrednosti efektivnih koeficijenata difuzivnosti jona Co2+ i Cs+.
