▎ 摘　　要

NOVELTY - A visible light active reduced graphene oxide (RGO)-iron based mixed oxide nanocomposite is synthesized by taking graphite oxide and ferric arsenate in 2:1 ratio, dispersing graphite oxide in water, sonicating and mixing with ferric arsenate, stirring mixture and irradiating in microwave to dryness, filtering precipitate through Whatman filter paper, washing with double distilled water 5-6 times, drying precipitate in air for overnight then in air oven at 60 degrees C for 18 hours. USE - Synthesis of visible light active reduced graphene oxide (RGO)-iron based mixed oxide nanocomposite for decomposition of pollutants in waste water. ADVANTAGE - Recombination time for waste water treatment is reduced.
