چکیده انگلیسی
H2O2 production plays an important role in electro-Fenton process for pharmaceutical and personal care products (PPCPs) degradation. In this work, carbon nanotube (CNT) was attempted to make a gas diffusion electrode (GDE) by rolling method to achieve a high H2O2 production and current efficiency, and it was further used as electro-Fenton cathode for the degradation of acetylsalicylic acid (ASA) as one kind of PPCPs. The optimal amount of catalyst layer was 0.15â¯g CNT and 93.75â¯Î¼L PTFE, obtaining the production of H2O2 of 805â¯mgâ¯Lâ1 in 0.05â¯mM Na2SO4 solution at 100â¯mA after 180â¯min. The degradation of ASA by electro-Fenton on such a CNT-GDE cathode was studied, and some important parameters such as current, pH as well as the dosage of Fe2+ were optimized. The degradation ratio of ASA could achieve almost 100% after 10â¯min and the TOC removal ratio was 62% at 1â¯h under the condition of 100â¯mA and pH 3, showing a great potential for the treatment of PPCPs.
