摘　　要：通过使用水热法制备TiO_(2)催化剂以不同盐酸投加量调控所得TiO_(2)形貌特征,以X射线衍射(XRD)、扫描电镜(SEM)、紫外-可见吸收光谱(UV-siv)对催化剂进行表征,考察其在不同反应条件下降解环丙沙星(CIP)的性能。结果表明2HCl-TiO_(2)在pH=7,投加量0.5g/L下2h光催化反应对环丙沙星的降解率达到97%。实验制得的2HCl-TiO_(2)催化剂经表征具有较高的稳定性,通过机理探讨降解环丙沙星的过程中·O_(2)-与·OH为主要活性物种。The TiO_(2)catalyst was prepared by hydrothermal method,and the morphology of the obtained TiO_(2)was controlled by different dosage of hydrochloric acid.The obtained catalyst was characterized by X-ray diffraction(XRD),scanning electron microscope(SEM)and ultraviolet-visible absorption spectrum(UV-siv),to investigate its performance in degrading CIP under different reaction conditions.The results showed that the degradation rate of ciprofloxacin reached 97%by photocatalytic reaction of 2HCl-TiO_(2)at pH=7 and dosage of 0.5 g/L for 2 h.The 2HCl-TiO_(2)catalyst prepared in the experiment was characterized by high stability,and the main active species were·O^(2-) and·OH in the process of degrading ciprofloxacin by mechanism.
