The invention relates to the technical field of water purification, and discloses an adsorbing material of high-strength carbon nanotube crosslinked hydrogel, which comprises the following formula raw materials and components: modified carbon nano tubes, beta-cyclodextrin-chitosan-polyacrylamide composite materials, acrylic acid, composite cross-linking agents and initiators. According to the adsorbing material of the high-strength carbon nano tube crosslinked hydrogel, the beta-cyclodextrin grafted chitosan is crosslinked with acrylamide chemical bonds and then crosslinked and polymerized with acrylic acid to form the hydrogel, and the hydrogel is rich in a large number of hydroxyl groups, amino groups, carboxyl groups and heavy metal ions Cu 2+ 、Cd 2+ And organic dyes such as methylene blue, rhodamine B and the like form coordination complex, the beta-cyclodextrin, the chitosan, the polyacrylamide and the acrylic acid are combined through chemical bonds instead of material crosslinking, the crosslinking degree of the hydrogel is enhanced, and the sodium alginate modified carbon nano-particlesThe tube improves the dispersibility and compatibility of the carbon nano tube and the hydrogel material, and improves the toughness and strength of the hydrogel material. |
