Synthesis of chitosan-Al2O3-Graphene oxide (GO) composite by sol gel method and its application with methylene blue has been conducted. This study was conducted to determine the ability of chitosan-Al2O3-GO composite in adsorbing methylene blue. Chitosan-Al2O3-GO composites were prepared with mass ratio (1:1), (1:2) and (1:3). These composites were characterized using XRD. The composite with th…
