The study was carried out with the goal of synthesizing composite bead of cellulose, chitosan
functionalized by sodium alginate using as an efficient and applicable adsorbent for methylene
blue removal. Fabricating parameters of the material synthesis process like cellulose mass, sodium hydroxide concentration, immersing time and sodium alginate concentration were assessed
in detail. The dye adsorption performance in water under the influence of pH, contact time, dye
initial concentration, the material mass, shaking speed, temperature was also thoroughly evaluated. The results of advanced analyses showed that the beads were successfully synthesized with a
rough surface and mesoporous structure. The adsorption isotherm and adsorption kinetics of dye
adsorption process exhibited that the process was consistent with the Freundlich adsorption
isotherm and the pseudo-second-order kinetic model, indicating a favorable physical adsorption
process with multilayer of the dye on the adsorbent surface. The intra-particle diffusion model
showed the strong dye adsorption by the beads occurred during the first two and half hours. The
adsorbent could maintain its adsorption performance of 86 % for three times of regeneration.
Finally, this study provided a recyclable and effective adsorbent for dyes separation from water.
