Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Fosfomycin pharmaceutical wastewater was treated by wet air oxidation (WAO). Two step first-order kinetics were used to investigate the removal of total organic phosphorus (TOP) and chemical oxygen demand (COD) in WAO of fosfomycin pharmaceutical wastewater. The effects of temperature and oxygen partial pressure on TOP and COD removal were quantified. Results showed that, two step first order kinetics could well describe TOP and COD removals. Generally, the removal rate of TOP and COD increased with increasing reaction temperature and oxygen partial pressure in both fast and slow reaction steps. And, the rate coefficients of the slow reaction step were found to be less sensitive to reaction temperature and oxygen partial pressure. According to Arrhenius equation, the activated energies for TOP oxidation were Eafast, 68.6 and Easlow 44.7 kJ/mol, and for COD removal were Eafast 41.0 and Easlow 24.5 kJ/mol at 1.0 MPa oxygen partial pressure.
