Synthesis of chitosan-GO composites using the sol-gel method and its application to methylene blue adsorption has been carried out. This study aims to determine the ability of chitosan-GO composites to adsorb methylene blue. Chitosan-GO composites were made with mass ratios (1:1), (1:3) and (1:5) and characterized by XRD. Material with a ratio (1:1) was chosen to be characterized using BET, SEM…
