NOVELTY - Synthesis of 0.5-1.5 atomic% fluorinated graphene oxide (FGO) involves, mixing n grams of graphite with solution of 5x n-40x n ml hydrofluoric acid and 50x n-150x n ml sulfuric acid or phosphoric acid with stirring at 30-80 degrees C for time (t1), adding 3x n-10x n g potassium permanganate to mixture and stirring the mixture at 40-80 degrees C for time (t2), adding reacted mixture to container containing 50x n-250x n ml ice and hydrogen peroxide, separating solid comprising 0.5-1.5 atomic% FGO from mixture, rinsing and drying the FGO. USE - Synthesis of fluorinated graphene oxide used for detection of heavy metal ions such as cadmium, lead, cupric, and mercury, and improvement in electrochemical sensing application. Can also be used for battery, biomedical device, capacitors, catalyst support and sensor. ADVANTAGE - The process provides FGO with improved electrochemical and structural properties. The heavy metal ion stripping is performed efficiently using metal-free FGO.
