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-EDS and used as methylene blue adsorption. Methylene blue adsorption process with several variables including contact time, concentration and temperature of methylene blue dye. The results of the XRD characterization of the chitosan-GO composite (1:1), (1:3) and (1:5) showed a diffraction peak at an angle of 2θ, namely 25.1°; 26.29° and 19.54°. The surface area of the chitosan-GO composite (1:1) with BET was 145.3505 m2/g. Characterization using SEM showed that the chitosan-GO (1:1) composite had a porous structure and not homogeneous. Optimum conditions for the adsorption ability of the chitosan-GO composite on methylene blue were obtained at 50 minutes contact time, maximum concentration of 60 ppm at 50°C. The adsorption process of the chitosan-GO composite on methylene blue followed the Freundlich adsorption isotherm with an adsorption capacity of 2.47 mg/g.
