GREEN SYNTHESIS AND CHARACTERIZATION OF GRAPHITE OXIDE BY ORTHOGONAL EXPERIMENT

Graphite oxide (GO) was prepared with graphite flakes, KMnO4, and a mixture of concentrated H2SO4/H3PO4 by an improved green synthesis method. To obtain fully oxidized GO, an orthogonal array design L9 was applied to select the optimum preparing conditions. The effects of the quantity of graphite, t...
