Eutrophication and PM2.5 being the largest visible issues due to the release of ammonia (NH3 & NH4+) into the environment, the energy consumed for the synthesis of ammonia is rather less concerned. In fact, for the production of ammonia from atmospheric nitrogen and for removing it from the environment, both consume a huge amount of energy. In this sense, draining ammonium into the water reservoirs and releasing the ammonia form into the atmosphere should not be the ultimate route of getting rid of these from various wastes. Draining of ammonium fertilizer along with the irrigation water is also causing energy loss globally. In this sense recycling the ammonia molecule can lead to a two-way energy saving: in the production as well as in the decontamination. It is now well known that the metal hexacyanoferrates, commonly known as the Prussian blue analogs (PBA), can adsorb both NH3 & NH4+ forms by two different mechanisms. So, we are studying the chemical and engineering aspects required for the utilization of these materials for the recycling of ammonia in various systems.
