Seawater uranium extraction adsorbent capable of self-renewing active antifouling coating and preparation method thereof |
| abstract |
The invention discloses a preparation method of a seawater uranium extraction adsorbent capable of self-renewing an active antifouling coating, which comprises the following steps: preparing zinc nitrate hexahydrate-polyacrylonitrile spinning precursor solution by utilizing polyacrylonitrile and zinc nitrate hexahydrate; spinning under certain conditions to prepare zinc nitrate hexahydrate-polyacrylonitrile fibers; adding zinc nitrate hexahydrate-polyacrylonitrile fiber into a 2-methylimidazole solution to react to obtain a 2-methylimidazole zinc salt porous coordination polymer-polypropylene composite fiber; crosslinking the composite fiber by using tannic acid to obtain a crosslinked 2-methylimidazole zinc salt porous coordination polymer-zinc nitrate hexahydrate-polypropylene composite fiber; finally, oximation reaction is carried out to obtain the amidoximated nano-scale composite fiber material for extracting uranium from seawater. The uranium extracting adsorbent for seawater prepared by the method not only can obviously improve the uranium extracting capacity, but also has continuously self-updated marine organism fouling prevention capacity in the cyclic uranium extracting process, and is free from shrinkage and stable in structure. |
