New Composite Materials for Decreasing of Radioactive Molecular Iodine in the Water Coolant on the Working and New Developed NPPS
Keyword(s):
The sorption of 131I−, 131IO3−, I2 and CH3131I from water solutions at 25°C 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 Kd 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 Kd more than 300 cm3/g at V/m = 100.
