This study enhanced wood-activated carbon using ammonia chemical vapor deposition (NH3-CVD) to improve its adsorption properties for carbamazepine (CBZ). Modification was done in a vacuum tube sintering furnace. We used X-ray photoelectron spectroscopy (XPS), Brunauer-Emmett-Teller (BET) method, and Fourier Transform Infrared Spectroscopy (FTIR) characterization analysis. Kinetic isothermal tests were carried out by UV spectrophotometry. NH3-CVD significantly increased the micropore volume surface area, notably W-6 sample, raised nitrogen content on surface. The capacity of modified activated (W-7) reached 130.81 mg/g, outperforming unmodified (W-0) at 72.46 mg/g. FTIR results indicated strong hydrogen bonding with CBZ molecules. modification improves wood increasing enhancing bonding, confirming single-layer heterogeneous
