| titleOfInvention | Graphene/sodium alginate bead of nano zero valence iron modification and its preparation method and application |
| abstract | The present invention provides a kind of preparation method and application of graphene/sodium alginate bead of nano zero valence iron modification, and method includes：Processing is modified to sodium alginate gel using prefabricated graphene oxide, and mixes nano zero-valence iron particle, by cross-linking and curing reaction, graphene oxide/sodium alginate bead that nano zero valence iron is modified is made；Handled again by thermal reduction, obtain graphene/sodium alginate bead of nano zero valence iron modification, which can be applied to the reduction reparation of Cr VI in water.The introducing of graphene can effectively facilitate the electron transmission between nano zero valence iron and pollutant, increase bead porosity, improve removal efficiency；Strengthen bead mechanical strength at the same time, reduce its percentage of damage in depolluting processes, reduce secondary pollution.Further, thermal reduction processing according to the present invention, can reduce the nano zero-valence iron particle being partially oxidized in embedding process again, so as to improve bead reactivity and disposal ability. |
