英文摘要	Directing to unwieldiness NOx emitted by the industry, the removal of NOx was implemented using yellow phosphorus (P-4) emulsion and red mud slurry as composite absorbent. Where yellow phosphorus is considered to stimulate formation of the ecological ozone (O-3) from O-2, the oxidation of insoluble NO into water-soluble NOx species by O-3, and the red mud as a pH buffer can be used to maintain the pH of the absorption liquid in a range that better absorbs NOx. NO is finally converted into NO2- and NO3-, whereas the yellow phosphorus is mainly PO43- . Single-factor influencing on the efficiency of denitration include the concentration of yellow phosphorus, reaction temperature, stirring intensity, gas flow rate, O-2 content, and red mud solid-liquid ratio were investigated. Response surface methodology (RSM) was used to optimize the process parameters. It was indicated that the removal rate of NOx can reach 99.3% under the optimal conditions. Moreover, the possible denitration reaction mechanism was also discussed.
