Although graphene oxide (GO) has been used in multidisciplinary areas due to its excellent physicochemical properties, environmental behavior and fate are still largely unclear. In this study, batch experiments, spectroscopy analysis theoretical calculations were addressed promote a more comprehensive understanding toward the coagulation of GO onto TiO2 under various conditions (pH, co-existing ions, temperature, etc.). The results indicated that neutral pH was beneficial removal...
The emerging radioactive pollution caused by human activity has attracted increasing attention in the recent years. Uranium (U(VI)) is one of key radionuclides environment, but its migration behavior firmly controlled sorption properties on environmental matrix. Herein, three hollow spherical materials (NiSiO, NiSiO@MgAl, and NiSiO@NiAl) were rationally designed constructed template method, which showed great potential immobilization U(VI). engineered functional nanomaterials exhibited fast...
