▎ 摘　　要

NOVELTY - The method involves treating graphene oxide with 20 kHz ultrasonic waves for 1-4 hours, dispersing the graphene oxide with deionised water, adding continuous galvanizing line dross to the dispersed graphene oxide, concentration of the continuous galvanizing line dross in the mixture being in the range of 4-20 wt. %, and mixing the mixture of graphene oxide and the continuous galvanizing line top dross with 1-10 molar sulphuric acid solution. The graphene oxide is produced by hummer method using graphite of 99% purity. The galvanizing dross includes zinc, aluminum, and iron. USE - Graphene sheet preparing method. ADVANTAGE - The produced grapheme nano sheets are stable in aqueous solution and can be easily isolated as monolayer or multilayer graphene sheets. DESCRIPTION OF DRAWING(S) - The drawing shows the transmission electron microscopy image of the graphene with dross.
