NOVELTY - A hybrid contains graphene and ferric oxide. USE - Hybrid is used for removing heavy metal e.g. arsenic, cadmium, mercury and antimony contained in effluent during wastewater treatment (claimed). ADVANTAGE - The wastewater treatment using hybrid is carried out efficiently. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for manufacture of hybrid, which involves manufacturing dispersed solution (A) by dispersing graphene and ferric oxide in water, adding iron in obtained dispersed solution (A) to obtain dispersed solution (B) having pH Of 8-11, maintaining temperature of dispersed solution (B) at 80-110? and adding reducing agent.
