AB  - As complex and difficult-to-degrade persistent organic pollutants (POPs), 
      antibiotics have caous damage to the ecological enused serivironment. Because of 
      the difficult degradation of antibiotics, sewage and sludge discharged by 
      hospitals and pharmaceutical enterprises often contain a large number of 
      antibiotic residues. Therefore, the harmless and resourceful treatment of 
      antibiotic sludge is very meaningful. In this paper, amoxicillin was selected as 
      a model compound for antibiotic sludge. Acidified red mud (ARM) was used to 
      degrade antibiotic sludge and produce hydrogen energy carrier formic acid in 
      catalytic wet peroxidation system (CWPO). Based on various characterization 
      analyses, the reaction catalytic mechanism was demonstrated to be the result of 
      the non-homogeneous Fanton reaction interaction between Fe(3)O(4) on the ARM 
      surface and H(2)O(2) in solution. Formic acid is the product of the 
      decarboxylation reaction of amoxicillin and its degradation of various organic 
      acids. The formic acid was produced up to 792.38 mg L(-1), under the optimal 
      conditions of reaction temperature of 90  degrees C, reaction time of 30 min, H(2)O(2) 
      concentration of 20 mL L(-1), ARM addition of 0.8 g L(-1), pH = 7, and rotor 
      speed of 500 rpm. This research aims to provide some references for promoting red 
      mud utilization in antibiotic sludge degradation.
