Synthesis, characterization, and performance of the Fe-HAp Bio heterogeneous catalyst for electro-Fenton degradation of cefuroxime sodium

Key Points

• The research aims to evaluate the performance of a Fe-doped bio-hydroxyapatite catalyst in the electro-Fenton degradation of cefuroxime sodium.
• Synthesis of Fe(iii)-doped bio-hydroxyapatite catalyst
• Characterization of the catalyst's properties
• Assessment of cefuroxime degradation under electro-Fenton conditions
• Evaluation of catalyst stability and reusability in reactions
• The Fe-doped catalyst effectively degrades cefuroxime via electro-Fenton reactions.
• ˙OH radicals are identified as the primary agents in the degradation process.
• The catalyst demonstrates high stability and can be reused multiple times.
• Combining electro-Fenton with aerobic biotreatment results in nearly complete mineralization of cefuroxime.
