▎ 摘　　要

NOVELTY - A graphene materials from sludge of wastewater treatment obtaining method involves performing pyrolysis on the water residuals in the absence of oxygenate at 700-1500 degrees C to obtain by-products, dispersing the remainder obtained from water or another dissolvent and exfoliating material, followed by removing residues that settle spontaneously, after centrifugation at speed of 8000 rpm, and recovering liquid phase material. USE - Method for obtaining graphene materials from sludge of wastewater treatment. ADVANTAGE - The method enables obtaining graphene materials from sludge with high yield, in simple, cost effective and environmentally friendly manner.
