The invention relates to a preparation method and application of a novel adsorbent Fe 2 O 3 @RF@GNFs, including first preparing Fe 2 O 3 , then modifying Fe 2 O 3 with RF resin to synthesize Fe 2 O 3 @RF, and finally using The modified GNFs synthesized Fe 2 O 3 @RF@GNFs‑x. In the present invention, RF resin is used to modify and synthesize Fe 2 O 3 /RF, the hydroxylated GNFs are hydrothermally treated with Fe 2 O 3 /RF to synthesize a new type of Fe 2 O 3 @RF@GNFs-x adsorbent, and the synthesized Fe 2 O 3 @RF and GNFs have increased specific surface area, improved material structure, and enhanced chemical stability, which are beneficial to their adsorption of pollutants and their adsorption performance is significantly enhanced. ‑ ), Congo red (CR), and phenol adsorption were significantly improved. |
