  • Abstract

This study investigated the adsorption capacity to remove C.I. 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. Reactive Red 35.
