Abstract

The invention relates to the field of antibiotic pollution degradation, in particular to a degradation method of chlortetracycline hydrochloride, which realizes effective degradation of chlortetracycline hydrochloride through electric activation sodium persulfate oxidation and electrochemical oxidation degradation treatment of chlortetracycline hydrochloride. Under the following optimized reaction conditions, the pH value of the chlortetracycline hydrochloride solution is 7, the concentration of chlortetracycline hydrochloride is 50 mg / L, and the concentration of sodium persulfate is 1.0 g / L; in the electrolytic reaction, an anode and a cathode are both platinum, the electrolytic current density is 50 mA / cm < 2 >, the reaction temperature is 30 DEG C, and after the reaction electrolysis is performed for 1 h, the degradation rate is as high as 97.70%, so that a better technical effect is achieved. Meanwhile, persulfate is activated through electrochemistry, the problem that metal ions exceed the standard due to metal dissolution of persulfate activated by traditional transition metal is solved, and environmental pollution is small. In addition, the method has the advantages of simplicity in operation, easiness in control, high stability, wide application range and the like.
