The main objective of this work was to assess the performance of combined processes, adsorption/ photodegradation of the ciprofloxacin antibiotic (CIP). Adsorption was achieved on natural hydroxyapatite (<i>nat-HA</i>) in the batch mode. The effect of pH (3–12), initial ciprofloxacin concentration (<i>C₀</i>, 25–200 mg L⁻¹), adsorbent dose (m, 0.25–3 g L⁻¹), and temperature (T, 298–328 K) on the ciprofloxacin adsorption capacity was studied. At 298 K, the maximum uptake of 147.7 mg g⁻¹ was observed with pH close to 8, 1 g L⁻¹<i>nat-HA</i> dose, and 150 mg L⁻¹ initial CIP concentration. Adsorption was effective, with a removal percentage of 82% within 90 minutes of contact time. For ciprofloxacin adsorption onto <i>nat-HA</i>, a pseudo-second-order kinetic model is well-suited. The Langmuir isotherm model successfully fit the experimental data and the process was spontaneous and exothermic. The coupling processes (adsorption/photocatalysis) were examined and found to be highly effective. For the remaining concentrations, the maximum degradation efficiency and mineralization yield were ~100% and 98.5%, respectively, for 1 mg L⁻¹ initial CIP. The combination of the strong adsorption capacity of natural hydroxyapatite and the high photocatalytic activity of TiO₂ can be an effective technique for removing fluoroquinolone antibiotics from wastewater.
