Cost-Effective Development of Nitrate Anchoring Sites on Charcoal for Low-Resource Communities to Filter Water (Full)
The study reports a two-step method for creating anchoring sites for nitrate on the surface of charcoal. The technologically simple process involves an acid treatment (HNO3, 1:10 dilution) followed by a heat treatment (800 °C) in a non-oxidizing atmosphere. The modified charcoal's surface chemistry, structure, and composition were characterized. Our research underscores the inefficacy of untreated charcoal in nitrate removal. In stark contrast, the acid treatment creates surface anchoring sites that effectively remove basic nitrate anions from water, lowering the nitrate concentration from 105 to 57.8 ppm (55% reduction in nitrate levels!).
