The impact of ammonia concentration and reducing agents on the ammonia oxidation performance of embedded nano-FeCu

Study on ammonia oxidation using nano-FeCu is very limited. NaBH4 is commonly used reducing agent for nanoparticle synthesis and regeneration, but it is toxic and costly. Thus, the objectives of this study are to investigate the performance of embedded nano-FeCu (eFeCu) in treating varied concentration of ammonia polluted water and identify the optimum dosage of FeCu for ammonia oxidation. The use of Na2CO3 as the replacement for NaBH4 is also investigated. Result showed that eFeCu converted ammonia to nitrogen gas when it was exposed to ammonia solution. Conversion from nitrate and nitrite to ammonia was observed in the first hour of reaction when eFeCu was exposed to
