Reactive Red 35 by three different adsorbent beads, consisting of pure chitosan and two different chitosan ⁄ titania (TiO₂) composite beads with the TiO₂ being obtained either from the sol-gel method or from added commercial TiO₂ (A100-TiO₂). From the obtained dye adsorption capacities, the chitosan ⁄ TiO₂ composite beads with A100- TiO₂ had the highest adsorption ability to remove reactive dye solution up to 97%, compared to the chitosan ⁄ TiO₂ composite beads with TiO₂ obtained from the sol-gel method (adsorption capacity of 70- 45%). This maybe because the A100-TiO₂ contained in the chitosan ⁄ TiO_2-sol composite beads was in the anatase crystalline form, while the TiO₂ obtained from the sol-gel method did not form a good anatase crystalline form, as shown by X-ray diffraction patterns and SEM micrographs. The crystallization of anatase formed in the composite beads enhanced the adsorption capacity of the composite beads. Pure chitosan adsorbent also showed a good adsorption capacity (95%) due to the electrostatic interactions between chitosan and C.I.
