Degradation of lomefloxacin hydrochloride through the activated peroxymonosulfate by bentonite-supported Co3O4
In this experiment,bentonite-supported Co3O4(Co3O4/Bent)was prepared and used to activate the peroxymonosulfate(PMS)for degradation of lomefloxacin hydrochloride(LOMH).The effects of reaction temperature,LOMH concentration and humic acid concentration on the degradation of LOMH were investigated.In addition,the degradation effects of the catalyst on tetracycline hydrochloride(TC-HCL),levofloxacin(LVFX)and ciprofloxacin(CIP)at different concentrations were also studied.The experimental results showed that when the reaction temperature was 40℃ and the concentration of LOMH was 10 mg/L,Co3O4/Bent showed the best degradation effect of LOMH,and the degradation ratio of LOMH at 60 min was 97.6%.Humic acid slightly inhibited the degradation of LOMH.Co3O4/Bent has a good degradation effect on TC-HCL,LVFX and CIP.
