| Nuclear power has been developed at high speed, which caused some environmental problem such as nuclear waste treatments. One of the problems is to treat radioactive wastewater properly.By simulating low-level liquid waste (LLW) and by batch and column experiments, lots of research on the effect of 60Co, 110mAg removal by ion exchange resins and novel inorganic ion exchange material from LLW with competitive metals ions at high concentration, has been done. In this paper, the exchange properties of radionuclide on materials were compared; the static isothermal adsorption curve and the static exchange capacity were measured. And by varying flow velocity and adding competitive metals ions (Ca2+, Mg2+, Na+, K+) into raw water, the effects of radionuclide removal by Carbonite and IRN160 exchange resins from LLW have been contrasted.The results show that: (1) Ion-exchange capacity of 732 resin, IRN160 resin and Carbonite for Ag+ is 54.92mg/g, 48.52 mg/g and 61.48 mg/g; and for Co2+ is 55.04mg/g, 63.02 mg/g, 64.68mg/g, respectively. ( 2 ) When competitive ions such as Na+, K+, Ca2+ and Mg2+ exist, Carbonite and IRN160 still show high removal rate for Ag+ and Co2+.(3)Flow rate is an important factor to column treatment,and 10BV/h is a good choice in removing nuclides in wastewater.(4)As a novel inorganic ion-exchange material, Carbonite has advantages in physical and chemistry property in radioactive wastewater treatment. Carbonite has good ion-exchange capacity, compared to 732 resin and IRN160 resin. Meanwhile, in presence of competitive ions, Carbonite remove Ag+ and Co2+ better, all of which indicate that it is suitable to be applied to remove Ag+,Co2+ in the radioactive effluents.
