This paper reports a new approach to treat the cobalt containing wastewater by in situ co-precipitation of Zn/Al layered double hydroxides (LDHs). LDHs with various metal compositions were characterized by XRD, and their capabilities to remove Co2+ were examined. Zn/Al system was found to be the best Co-removing LDHs system, which could remove Co2+ at the highest efficiency (> 99.99%). Reaction parameters of Zn/Al-LDHs were further optimized. The analysis of products found that Co2+ were removed in the form of Co4.8Zn1.2Al2(OH)16CO3·4H2O. This study suggests that in situ co-precipitation Zn/Al-LDHs provides an effective approach to treat liquid radioactive wastes containing Co2+ from nuclear power plant.
