Practical applications of inorganic adsorbents for on-site radioactive waste water treatment were investigated. Two kinds of radwaste water, Mo-99 and waste ethylene glycol, were treated to remove radionuclides at INER by adsorption via commercial and customized adsorbents. Treatment facilities, procedures and capacities of adsorbents are described and discussed. Two inorganic adsorbents, Cs-Treat and Sr-Treat, were commercially obtained for Cs-137 and Sr-90 removal in the Mo-99 waste water treatment. Self-designed AC-Sr, commercial DT-30 and NRW160 were applied for waste ethylene glycol treatment via filled adsorbent columns. Capacities of commercial and customized adsorbents for various radionuclides were investigated to compare the performance of INER-developed adsorbents with commercial ones for future application.
