摘要

The degradation of oxytetracycline (OTC) by the iron wire/H_2O_2 system was investigated. The effects of initial concentration of OTC, H_2O_2 dosage, initial pH value, iron wire dose and reused times of iron wire on the degradation of OTC were examined. The results showed that iron wire exhibited high catalytic activity and stability on the activation of H_2O_2 for the degradation of OTC. The degradation kinetic of OTC could be well described by the pseudo first-order kinetic model. The reactive oxygen species (·OH) produced in the iron wire/H_2O_2 system is significant key to the degradation of OTC. The mechanism of oxidative degradation of OTC was discussed by the UV-Vis spectra analysis and monitoring the iron ions dose and pH value of the reaction solution.
