Abstract

In order to solve the problem of poor removal effect of traditional wastewater treatment technology on the ibuprofen pollutant,the AC@Ti-F GDE electro-peroxone system is constructed to strengthen the oxidation efficiency of traditional electro-peroxone system and provide a new idea for subsequent electro-peroxone technology of ibuprofen degradation. The results show that the relative content of HO^• in the microporous titanium-foam air diffusion electrode(Ti-F GDE)is increased by 155. 7% compared with the traditional electrode(Ti-F GDE),and the relative content of HO^• in the AC@Ti-F GDE system is further increased by 35. 4% compared with the Ti-F GDE system after the activated carbon is added. It is attributed to the enhanced H₂O₂ accumulation within the AC@Ti-F GDE system. By adjusting the dosage and particle size of activated carbon,the optimal dosage and particle size of activated carbon for AC@Ti-F GDE electro-peroxone system are 0. 8 mg/cm³ and 850 μm,respectively. The AC@Ti-F GDE electro-peroxone system is applied to the treatment of ibuprofen. The mechanism of degradation mineralization is deduced according to the changes of small and medium molecular acids and liquid mass spectrometry.
