  • Nanocomposite hydrogels and methods of using same in purifying a fluid
    Patent number: 11305258
    Abstract: There is provided herein a method for preparing a graphene oxide (GO) hydrogel. The method comprises the steps of adding vitamin C (VC) to a dispersion GO in a ratio GO:VC varying from 1:50 to 1:300; and incubating at a temperature above 45° C., preferably at 95° C. the dispersion for a time sufficient for a porous hydrogel to be self-assembled from the dispersion. CNPs can also be added to the hydrogel in a ratio GO:CNPs from 4:1 to 1:1. There is also provided the hydrogel so obtained and its use for removing contaminants from a fluid. The hydrogel can also be used as a filter for such decontamination.
