摘要： Orthogonal experiments were used to simulate the enrofloxacin (ENR) elimination dynamic in deeper water of aquaculture. Two factors at values common in fishery water (temperature of 20 degrees C, 25 degrees C, and 30 degrees C; pH of 5, 7, and 9) were studied. The degradation of ENR in the nine treatment groups ranged from 44.7 to 80.1%. Variance analysis indicated that pH had a strong impact on the elimination of ENR, while temperature changes showed little effect. The ENR removal rate was highest at a combination of 25 degrees C and pH 5. The optimal conditions of eliminating ENR were performed for exploring the generation of ciprofloxacin (CIP), which indicated that higher ENR concentrations led to the production of greater amounts of CIP. The half-time of ENR was increased 2.02-times in the ENR concentrations increasing from 20 to 2000 ng/mL. This study could increase our understanding of the behaviors of ENR and CIP during the aquaculture process.
