▎ 摘  要

NOVELTY - Preparing attapulgite-reduced graphene oxide aerogel involves adding 1 grams attapulgite to 20 milliliter deionized water, ultrasonically treating for 1 hours, stirring for 1-5 hours and adjusting the pH value to 4. The reaction mixture is dropwise added with 2 mol/liter aluminum salt solution, while keeping the pH value of the solution in between 4-6. The mass ratio of aluminum salt solution and attapulgite is 1:2-1:30. The mixture is stirred for 1 hour, adjusted the pH value to 7, stirred for another 1 hour, again the adjusted the pH value to 9 and again stirred for 1 hour. USE - Method for preparing attapulgite-reduced graphene oxide aerogel (claimed). ADVANTAGE - The method enables to prepare attapulgite-reduced graphene oxide aerogel, which has adsorption efficiency.
