摘要

The removal effect of Fe/N co‐doped biocarbon materials (Fe/N‐ACs) in catalytic persulfate‐catalyzed degradation of tetracycline hydrochloride (TC) was studied in order to seek a catalyst with high catalytic activity in antibiotic wastewater treatment. Using melamine and ferric nitrate as nitrogen source and iron source, respectively, and using distiller's grains as carbon source, the Fe/N‐ACs catalysts with different nitrogen content ratios and different calcination temperatures were prepared by the method of blending grinding and carbon dioxide activation. Then it was used to analyze its removal effect on TC. Activated carbon (AC) prepared from distiller's grains alone catalyzed the decomposition of 25.0% of TC, which was proportional to the removal of TC with the increase of nitrogen content and calcination temperature. When the Fe content is 5%, the melamine content is 20%, and the calcination temperature is 850 °C, the catalyst has good catalytic performance. Under optimal conditions, after 1h of reaction, the removal rate of TC can reach 61.1%. Fe/N‐ACs have a synergistic effect on catalyzing persulfate.
