Ammonia capture from wastewater with a high ammonia nitrogen concentration by water splitting and hollow fiber extraction

Abstract Water contamination caused by ammonia effluents has become a critical environmental issue. In this study, a coupled system of water splitting and hollow fiber extraction was proposed for highly efficient ammonia capture from wastewater that has a high ammonia nitrogen concentration. Our results showed that the ammonia capture ratio reached >99%, while the ammonia nitrogen concentration in the wastewater decreased to
