Research on the application potential of spent biological activated carbon from BAC process to remove radionuclides Sr 2+ from water

The spent biological activated carbon (SBAC) as solid waste is used to study the removal of radioactive Sr2+ in water. The results show that SBAC adsorbs Sr2+ reaching equilibrium within 3 min and the adsorption is an exothermic reaction. The removal rate can reach more than 85%, desorption rate is less than 6.16%, and it can also achieve 40% removal in river water. The three-round regeneration efficiencies are all ~ 100%. The adsorption process is without secondary pollution. SBAC has good potential for the removal of radioactive Sr2+ in water.
