Abstract

Onečišćenje podzemnih voda nitratima, koje je uglavnom uzrokovano primjenom dušičnih gnojiva u intenzivnoj poljoprivredi, raširen je problem diljem svijeta i potencijalni rizik za ljudsko zdravlje. Kako bi se riješio ovaj problem zagađenja razvijaju se različite metode pomoću kojih se štetni nitrati mogu ukloniti iz voda. Jedna od tih metoda je elektrokatalitička redukcija nitrata kojom se nitrati prevode direktno u amonijak. Pomoću ove metode smanjuje se razina onečišćenja u podzemnim vodama, ali ujedno se dobiva i koristan produkt amonijak koji se može dalje iskorištavati u poljoprivrednoj uporabi.

Abstract (english)

Groundwater pollution with nitrates, which is mainly caused by the application of nitrogen fertilizers in intensive agriculture, is a widespread problem worldwide and a potential risk to human health. In order to solve this pollution problem, various methods are being developed by which harmful nitrates can be removed from water. One of these methods is the electrocatalytic reduction of nitrates, which converts nitrates directly into ammonia. Using this method, the level of pollution in underground water is reduced, but at the same time a useful product, ammonia, is obtained, which can be further exploited in agricultural use.
