NEW COMPOSITE MATERIALS FOR DECREASING OF RADIOACTIVE MOLECULAR IODINE IN THE WATER COOLANT ON THE WORKING AND NEW DEVELOPED NPPS
The sorption of 131I-, 131IO3-, I2 and CH3131I from water solutions at 25℃ on new composite materials obtained by modifying of cation-exchange resin KU-2 was investigated. It was established, that the given materials are capable to absorb I2 both from distilled water, and from a water coolant of the WWER-type NPPs, with distribution factors Кd more than 103 cm3/g at V/m=100. Thus, it was found, that practically full I2 absorption (more than 95.0%) was achieved for 15 min. It was shown, that anion-exchange resin AV-18 is capable to adsorb CH3131I from a water solutions with distribution factors Кd more than 300 cm3/g at V/m=100.
