Study on Fiber Optical Reactor Catalytic Degradation of Oxytetracycline

Abstract:

Antibiotics have played a positive role in human health and. But underutilized antibiotics can’t be removed by normal treatment. The paper study the impact of fiber optical reactor catalytic degradation of oxytetracycline and step to examine the degradation effect. The results show that: temperature increases within a certain range contribute to the degradation of the oxytetracycline. Effects of pH on the photocatalytic reaction were significant, and alkaline conditions is more conducive to oxytetracycline photocatalytic degradation. In the concentration range of the experimental study, oxytetracycline photocatalytic degradation was inhibited by the higher initial concentration. Catalyst promoted oxytetracycline degradation, its addition amount on photocatalytic reaction influence is relatively large, when the pH is 7, with the increase of nano-TiO₂ dosage, removal rate was gradually increased. The degradation rate of oxytetracycline in different reaction process can be shown as: photocalysis＞photolysis＞hydrolysis in this research.
