Chitosan/cellulose/TiO2 composite films had been prepared and were used for metanil yellow removal. Cellulose was isolated from alang-alang grass (Imperata cylindrica). The addition of TiO2 aims to provide photocatalytic activity of the composite. Chitosan/cellulose/TiO2 composite films were characterized by FT-IR, XRD, SEM, tensile strength, and DSC. The addition of cellulose and TiO2 to chitosan caused a decrease in crystallinity and improved mechanical and thermal properties of chitosan. The study of metanil yellow removal was conducted with several parameters such as pH, dye concentration and contact time. The result showed that the process of metanil yellow removal was influenced by the pH of the solution. The best removal process was obtained at pH 3 and contact time of 100 minutes. Based on adsorption kinetics and isotherm studies, the removal of metanil yellow by chitosan/cellulose/TiO2 composite film was in accordance with the pseudo second order model and Langmuir isotherm.
