▎ 摘　　要

NOVELTY - Purifying graphene-coated single diamond nano-particles involve subjecting mixture to magnetic separation, acidification, oxidation, alkalization and heavy liquid separation. The mixture is subjected to oxidation under normal temperature and pressure conditions using an alkaline solution. After alkalization, the mixed solution is filtered and washed to remove silicon. USE - Method for purifying graphene-coated diamond nano-particles (claimed). ADVANTAGE - The method enables efficient purification of graphene-coated diamond nano-particles in a cost effective manner. DESCRIPTION OF DRAWING(S) - The drawing shows schematic representation of method for purifying graphene-coated diamond nano-particles. (Drawing includes non-English language text).
