Abstract

Abstract

Electrochemical oxidation is an efficient and environmental-friendly technology with significant advantages in the treatment of antibiotics including amoxicillin. The traditional two-dimensional electrode reactor packed activated carbon as particle electrode will reduce the mass transfer resistance in the system and improve current efficiency. This study explored the optimal conditions for the treatment of amoxicillin simulated wastewater by a three-dimensional electrode reactor, and compared with a two-dimensional electrode reactor and the adsorption process. The optimal conditions were as follows: the quartz sand accounted for 10% of the total volume of the packed particles, the current density was 5 mA/cm², the electrolyte was 17 mmol/L Na₂SO₄, and the initial pH of the solution was 5.56. Under the optimal condition, the TOC removal rate was 49.1%, and the amoxicillin removal rate was 99.0%. The synergy between electrolysis and adsorption in the three-dimensional electrodes reactor made the TOC removal rate higher than that of adsorption and traditional two-dimensional electrode reactor (49.1%>22.0%+8.7%), showing a good application prospect.
