▎ 摘　　要

NOVELTY - Preparing acetylacetone reduced graphene, comprises (i) taking oxidized graphene in a beaker, adding deionized water, and ultrasonically dispersing, (ii) adding the oxidized graphene aqueous solution in round bottomed flask bottle, adding acetylacetone, adding aqueous ammonia for regulating pH to alkaline, and refluxing, (iii) filtering, washing using methanol, and acetone, washing again once using methanol, and (iv) finally vacuum drying to obtain the graphene powder. USE - The method is useful for preparing acetylacetone reduced graphene (claimed), which is used in absorbing heavy metal ion, sewage treatment and drinking water purification. ADVANTAGE - The method uses economical and environmentally friendly acetylacetone reducing agent having low toxicity, and metal ion complexing action for preparing graphene for absorbing heavy metal ion. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for acetylacetone reduced graphene according to the above mentioned method.
