Recyclable ammonia adsorbent using Prussian blue analogue

摘要

Environmental issue on ammonia(NH3) has been growing. NH3 released into the air combines NOx or SOx, resulting in the fine particles of NH4 salt, which is main component of the PM2.51. In addition, NH3 from livestock sector often causes malodour problems. In the case of malodour, the concentration of ammonia should be kept less than 25 ppmv for both human worker and livestocks. Adsorption removal is one of the promising decontamination techniques for trace concentration. Adsorption is one of the most common process for trace gas removal.
