Effect of pH on Green Synthesis of Reduced Graphene Oxide Using Lemon Extract and Application of Fe3O4/RGO nanocomposites for the removal of Pb (II) from aqueous solution

Maryam Ghasemi; Javad Azimi-Amin

Volume 7, Issue 1 , April 2022, Pages 101-120


  Here, graphene oxide was synthesized and reduced by lemon extract (source of vitamin C) in an aqueous solution under different pH (3 and 10). The lemon extract was prepared using a solvent-free method. The proposed mechanisms for the reduction of GO may be due to the nucleophilic attack of oxygen anion ...  Read More
