TiO₂-hydroxyapatite nanocomposites were prepared by the simultaneous gelation of titanium alkoxide and precipitation of a re-dissolved natural phosphate mineral in ammonia and tested for drug degradation in solution under UV light. Pharmaceuticals were preferentially adsorbed on the apatite-rich composites, whereas their photodegradation was more effective in the TiO₂-rich phases. At high TiO₂ content, the efficiency of photocatalytic degradation of nanocomposites is better compared to that of TiO₂related to the antibiotic affinity. Using 40TiHAp as photocatalyst, ciprofloxacin and ofloxacin were 100% photodegraded within 15 min and 120 min, respectively. The proposed nanocomposites are efficient catalysts for the enhanced adsorption and photocatalytic degradation of ciprofloxacin and ofloxacin in water.

TiO _2-羟基磷灰石纳米复合材料是通过同时胶凝烷氧基钛和在氨水中沉淀再溶解的天然磷酸盐矿物制备的，并在紫外光下测试了药物在溶液中的降解。药物优先吸附在富含磷灰石的复合材料上，而它们的光降解作用在富含TiO _2的相中更为有效。在高TiO ₂含量下，纳米复合材料的光催化降解效率优于TiO _2。与抗生素亲和力有关。使用40TiHAp作为光催化剂，环丙沙星和氧氟沙星分别在15分钟和120分钟内被100％光降解。所提出的纳米复合材料是用于增强环丙沙星和氧氟沙星在水中的吸附和光催化降解的有效催化剂。
