Modified Nanocellulose-Based Adsorbent from Sago Waste for Diclofenac Removal

A nanocellulose-based adsorbent was successfully synthesized via a hydrothermal process. It characterized by X-ray diffraction, Fourier Transform Infrared Spectroscopy, Field Emission Electron Microscopy and Brunauer–Emmett–Teller surface area analysis. Photocatalysis has the best potential to replace conventional wastewater treatment technology through photodegradation of organic contaminants. This study focuses on preparation photocatalytic nanocellulose prepared from sago waste for removal diclofenac industrial wastewater. Its activity evaluated degradation (100 mg/L) under ultraviolet (UV) light. The effect different loadings TiO2 kinetics investigated. To its removal, experiments were carried out UV light with contact times ranging 30 120 min at room temperature. maximum percentage found be 57.5% 200 µL TiO2, this increased up 82.4% 800 TiO2. capacity 13.3 mg/g. well fitted “pseudo-first order model” (PSO). Kinetic analysis using PSO model 100 ppm sodium gave value equilibrium adsorption capacity, qe 13.52 calculated mg/g non-linear regression plots. obeyed pseudo-first-order reaction lowest AICc, RSME values 0.56 0.53 highest correlation coefficient, R2, 0.99. Three models current data, their suitability inferred as following: > pseudo-second-order Langmuir–Hinshelwood.
