Zero-valent iron and biochar composite with high specific surface area via K2FeO4 fabrication enhances sulfadiazine removal by persulfate activation

Zero-valent iron and biochar composite (ZVI/BC) is a prospective catalyst for activating persulfate and specific surface area (SSA) of ZVI/BC is one of the most important factors affecting its efficacy in the removal of environmental contaminants. However, the green fabrication of ZVI/BC with large SSA remains a challenge. In this study, ZVI/BC with a highly porous structure and large SSA fabricated by co-pyrolysis of K2FeO4 and bamboo was...
