摘要：

针对传统类Fenton法需在低pH范围内反应、催化剂难分离等问题，提出采用水热合成法制备了以铜基为核心的非均相类Fenton催化剂Cu/Co，并对其进行表征。实验结果表明：制备的催化剂Cu/Co主要组分是CuO，对环丙沙星（CIP）具有较高的催化活性和重复利用性。在最优条件下，CIP的降解率达到94.7%。所制备的催化剂Cu/Co能够在pH为4.0~8.0的条件下保持较好的反应活性，且催化剂Cu/Co-500重复使用5次后，对CIP的降解率依旧能达到81.7%，具有良好的循环使用性。

Abstract:

The traditional Fenton method has disadvantages, such as reaction in a low pH range and difficult separation of catalyst. In this study, a heterogeneous Fenton-like catalyst Cu/Co with copper as the core was prepared by hydrothermal synthesis method and characterized. The experimental results showed that the main components of the prepared catalyst Cu/Co were CuO, which had high catalytic activity and reusability for ciprofloxacin. Under the optimal conditions, the degradation rate of ciprofloxacin reached 94.7%. The prepared catalyst Cu/Co could maintain good reaction activity at pH 4.0-8.0, and the catalyst could still catalyze and degrade ciprofloxacin to reach a removal rate of 81.7% after being reused for 5 times, thus having good recycling property.

Key words: Fenton-like, copper-based catalyst, hydrothermal synthesis, ciprofloxacin
