Ciprofloxacin, a widely used fluoroquinolone antibiotic, is found in drinking water as a pseudo-persistent pollutant. Zeolitic octahedral metal oxide based on ε-Keggin ironmolybdate (MoFeO) is synthesized as an efficient catalyst for ciprofloxacin degradation with H₂O₂. Higher than 80% of ciprofloxacin is degraded in the pH range from 5 to 8, and the highest degradation percent is achieved at pH 8. The catalyst shows high stability as a heterogeneous catalyst and can be reused up for 3 times in continues ciprofloxacin degradation. Presence of humic acid has no effect on the ciprofloxacin degradation catalyzed by MoFeO, and ciprofloxacin is efficiently degraded in the water from city tap, river, pond, lake, and sea with various dissolved organic matter concentrations and conductivities.

环丙沙星是一种广泛使用的氟喹诺酮类抗生素，在饮用水中被发现是一种伪持久性污染物。合成了基于ε -Keggin 钼酸铁 (MoFeO) 的沸石八面体金属氧化物，作为环丙沙星用 H ₂ O ₂降解的有效催化剂. 高于80%的环丙沙星在pH值范围为5-8时降解，在pH值为8时降解率最高。该催化剂作为非均相催化剂表现出高稳定性，在环丙沙星连续降解过程中可重复使用3次。腐植酸的存在对MoFeO催化的环丙沙星降解没有影响，环丙沙星在来自城市自来水、河流、池塘、湖泊和海洋的各种溶解有机物浓度和电导率的水中被有效降解。
