▎ 摘  要

NOVELTY - Method for preparing graphene oxide composite aluminum-based lithium adsorbent, involves adding 8-20 pts. wt. graphene oxide, 6-15 pts. wt. aluminum chloride salt, 1-5 pts. wt. lithium salt, 15-40 pts. wt. water, ultrasonically shaking for 15-60 minutes, controlling the water temperature at 40-80 degrees C, adding 1-10 mol/l lye while stirring, controlling the lye feeding time to 15-60 minutes, stopping adding lye when the pH value of the solution is 4.5-7, after finishing the reaction, filtering, and drying to obtain the product. USE - The method is used for preparing graphene oxide composite aluminum-based lithium adsorbent (claimed). ADVANTAGE - The aluminum-based lithium adsorbent has a large specific surface area and a large adsorption capacity.
