Synthesis and characterization of graphite oxide and 2-methyl-4-chlorophenoxy acetic acidgraphite oxide (mcpa-go) nanocomposite with its controlled release property / Norilyani Izzati Hasanuddin

The graphite oxide and 2-methyl-4chlorophenoxy acetic acid- graphite oxide (MCPA-GO) nanocomposite were successfully synthesized by using improved Hummer's method and ion-exchange method respectively. In this study, MCPA-GO nanocomposite was synthesized at various concentration of MCP A rangin...
