▎ 摘  要

NOVELTY - Preparing high-strength copper catalyst alginic acid aerosol, comprises (i) adding graphene oxide into distilled water, ultrasonic dispersing until a uniform, adding sodium alginate and polyacrylamide, and mechanical stirring until they are mixed uniformly, (ii) dropping the obtained mixed solution into a mold, immersing the mold into water-soluble metal salt solution, (iii) placing the metal salt solution in constant temperature water bath, reacting at a certain temperature to obtain hydrogel, (iv) washing the hydrogel by distilled water until removing an external surface metal ion. USE - The method is useful for preparing high-strength copper catalyst alginic acid aerosol (claimed). DETAILED DESCRIPTION - Preparing high-strength copper catalyst alginic acid aerosol, comprises (i) adding graphene oxide in distilled water, ultrasonic dispersing until a uniform, adding sodium alginate and polyacrylamide, and mechanical stirring until they are mixed uniformly, (ii) dropping the obtained mixed solution into a mold, immersing the mold into water-soluble metal salt solution, (iii) placing the metal salt solution in constant temperature water bath, reacting at a certain temperature to obtain hydrogel, (iv) washing the hydrogel by distilled water until removing an external surface metal ion, and placing in refrigerator at -10 degrees C pre-freezing for 10 hours, (v) placing the good pre-freezing the hydrogel into the freeze dryer, drying to obtain the product.
