Abstract
The invention belongs to the technical field of environmental remediation materials, and relates to enteromorpha hydrogel for rapidly removing pollutants as well as a preparation method and application of the enteromorpha hydrogel, the preparation method comprises the following steps: (1) removing impurities from enteromorpha, cleaning, freeze-drying, crushing, screening with a 90-120-mesh screen to obtain large-particle-size enteromorpha powder, and screening with a 300-500-mesh screen to obtain small-particle-size enteromorpha powder; (2) dissolving chitosan in an acetic acid aqueous solution, adding the large-particle-size and small-particle-size enteromorpha powder into the acetic acid aqueous solution, and stirring to obtain a mixed solution; (3) dropwise adding a cross-linking agent into the mixed solution while stirring, and freeze-drying after gel is formed; and cleaning to obtain the enteromorpha gel. The high-strength enteromorpha hydrogel is prepared by interpenetrating network crosslinking of enteromorpha with different particle sizes and a natural biological material chitosan, and a new composite material is provided for removal of pollutants; the method can be used for removing methyl orange dye in a water environment; meanwhile, the problems that existing enteromorpha is difficult to utilize, deep processing is needed in the preparation process and the like are solved.
Description
technical field [0001] The invention belongs to the technical field of environmental remediation materials, and in particular relates to a prolifera hydrogel for rapid removal of pollutants and a preparation method and application thereof. Background technique [0002] In recent years, the influence of proliferative proliferation on the marine ecological environment has attracted much attention. The distribution area of prolifera is expanding year by year. Most of the salvaged prolifera can only be landfilled and cannot be used well. Moreover, the landfill will cause problems such as soil salinization and water pollution. , is not a long-term solution. Therefore, how to make full use of prolifera and turn waste into treasure is the top priority of maintaining the marine environment and promoting sustainable development. Using prolifera as a raw material to prepare and apply hydrogels can provide a new idea and possibility for the treatment of prolifera. Hydrogel is a cr...
