Abstract

We report on the application of an innovative whey protein amyloids-carbon hybrid filter for the removal and disposal of the long-lived radioactive fission product 137Cs from aqueous samples. Test experiments revealed a reduction of 137Cs radioactivity by a factor of 340 compared to the initial solution, with an efficiency as high as 99.7%. The adsorption capacity of the membrane was explored by performing several cycles of filtration, indicating a potential retention of more than 115 MBq per gram of filtering material at the applied experimental conditions. These results pave the way for further investigations on the applicability of this filter material to other nuclear fission products.
