Abstract:- Ashes of leaves of Azadiracta Indica, Phyllanthus Neruri, Annona Squamosa, Moringa Tinctoria, Tridox Procumbens and Calotropis Zygantia have been probed for their sorption abilities towards Nitrates using simulated polluted waters. At low pH values, these sorbents are found to be effective. The physicochemical parameters such as pH, time of equilibration and sorbent concentrations are optimized for the maximum removal of Nitrates. Methodologies have been developed for the extraction of good quantities of Nitrates. More than 90% removal of Nitrate has been found to be possible with simulated waters at optimum conditions of extractions. Fivefold excess of cations like Ca2+, Cu2+, Zn2+ and Mg2+ are synergistically increasing the extraction, while Sulphates is interfering markedly but other anions: Carbonates, Chlorides, Fluorides and Phosphates are marginally interfering. The procedures developed are successfully applied for the polluted lake water samples.
Key words:- Nitrates; pollution control; bio-adsorbents; applications. |
