description: The deterioration of water quality due to industrial wastewater, particularly  from dyes such as methylene blue, has driven the need to develop effective and  environmentally friendly adsorbent materials. This study aims to isolate nanocellulose  from oil palm empty fruit bunch (OPEFB) waste, synthesize composite beads  based on nanocellulose, mesoporous silica, and sodium alginate, and investigate the  adsorption mechanism of methylene blue. Nanocellulose was obtained through a  series of processes including delignification, bleaching, TEMPO-mediated oxidation,  and ultrasonication, and subsequently synthesized into beads using an ionic  gelation method with CaCl₂. Characterization was carried out using FTIR, XRD,  SEM, TEM, and TGA, while adsorption experiments included variations in contact  time, adsorbent dosage, solution pH, and Isoterm analysis. The results showed that  nanocellulose was successfully isolated with an average diameter of 3,83 nm and  possessed active functional groups that support the adsorption process, while the  resulting composite beads exhibited a stable structure and porous morphology. The  contact time study indicated that adsorption occurred rapidly at the initial stage and  reached equilibrium at 180 minutes. Increasing the adsorbent dosage enhanced adsorption  efficiency due to the greater availability of active sites on the adsorbent  surface. Adsorption performance was influenced by operating conditions, with optimum  results at pH 7, and followed the Freundlich Isoterm model, indicating a  heterogeneous surface characteristic.Overall, nanocellulose-based composite beads  derived from OPEFB demonstrate significant potential as an effective and sustainable  adsorbent for dye wastewater treatment.
