- Abstract:
- To solve the problem of residual pesticide and bacteria on fruits and vegetables in households, boron-doped diamond (BDD) film electrode was used to degrade the target contaminants diuron and isoprocarb, and the removal performance of Staphylococcus aureus was explored. The BDD film electrode was capable of effectively removing diuron, isoprocarb and Staphylococcus aureus from water, and its degradation (or inactivation) rates were 99%, 87% and 99.9%, respectively. The electrolytes in water (chloride ions, sulfate and bicarbonate) inhibited the degradation of pollutants to varying degrees by affecting the yield of active ingredients (ozone, hydroxyl radicals, etc.). Based on the analysis of degradation products, it was speculated that the hydroxylation of aromatic ring was the main degradation pathway of the target pollutants, and the acute toxicity of diuron and isoprocarb gradually decreased during the degradation process of the BDD film system. The BDD film electrode device applicable to the end of faucet effectively ensured the drinking water safety for users.
