The removal of concentrated fluoride in acidic wastewater by the conventional Ca(OH) 2 method is challenged by the insufficient efficiency and difficult separation of fine CaF 2 precipitate. Herein, we construct a strategy to tackle these challenges by coupling zero-valent iron (ZVI) with Ca(OH) 2.ZVI reduces fluoride concentration from 12,000 to 3980 …
