Method for degrading ciprofloxacin through ozone oxidation by using manganese-cerium bimetallic supported alumina catalyst

The invention discloses a method for degrading ciprofloxacin through ozone oxidation by using a manganese-cerium bimetallic supported alumina catalyst. The method comprises the following steps: (1) activating an alumina carrier; (2) impregnating the activated alumina carrier by using a manganese cerium salt solution; and (3) drying and calcining the impregnated alumina carrier to obtain the manganese-cerium bimetallic loaded alumina catalyst. And (4) mixing the manganese-cerium bimetallic loaded alumina catalyst, ozone gas and a solution containing ciprofloxacin, and carrying out a reaction so as to complete oxidative degradation of ciprofloxacin. Therefore, by adding the manganese-cerium bimetallic loaded aluminum oxide catalyst in the reaction of oxidizing and degrading the ciprofloxacin by the ozone, the utilization rate of the ozone is remarkably improved, the degradation rate of the ciprofloxacin is remarkably improved, the ciprofloxacin polluted water body is efficiently, reliably and economically treat
