Chloramphenicol, a widely used antibiotic, is persistent pollutant in aquatic environments, posing threat to both human health and ecosystems. This study investigates the use of calcium oxide (CaO) derived from marine coral fragments as natural adsorbent for removal chloramphenicol water. Marine was calcined obtain CaO, which then characterized using techniques such X-ray fluorescence (XRF) Fourier-transform infrared spectroscopy (FTIR). Chloramphenicol detected at maximum absorption wavelength 278 nm UV-Vis spectroscopy. The adsorption efficiency CaO tested by varying weights (0.05 g, 0.075 0.1 g) concentrations (5, 10, 15, 20, 25 mg/L). Results indicated that an weight 0.05 g most effective, achieving 7.05%. highest capacity, 0.28 mg/g, observed concentration 20 ppm. However, overall relatively low, indicating need further development, creation biocomposites, improve its capabilities. demonstrates while coral-derived shows potential eco-friendly adsorbent, additional research optimization are necessary enhance effectiveness water treatment applications.
