Abstract
Invenţia se referă la domeniul epurării apelor şi anume la micşorarea concentraţiei de nitriţi în apa potabilă.Esenţa invenţiei constă în faptul că se propune un procedeu de purificare a apei potabile de nitrit-ion, care include prelucrarea apei cu un reducător, caracterizat prin aceea că în calitate de reducător se utilizează acidul ascorbic în următorul raport molar [AAs]: [NO2] = 10:1, în acelaşi timp purificarea apei efectuându-se timp de 30-40 min.Rezultatul tehnic al invenţiei constă în aceea că acidul ascorbic interacţionează cu cationul de nitrozoniu, transformându-l în agent neactiv denitrozat şi anume oxidul de azot(II) şi micşorând concentraţia de nitrit-ion în apa potabilă de 10 ori, ceea ce duce la ameliorarea ei.
