Ashes of leaves of Phyllanthus neruri, Azadiracta indica, Annona squamosa, Moringa tinctoria, Calotropis zygantia and Tridox procumbens have been probed for their sorption properties towards Nitrite ions. Batch methods of extractions have been adopted using simulated waters. Various physicochemical parameters such as pH, sorbent dosage and time of agitation have been optimized for the successful quantitative extraction of Nitrite. The methodologies are successfully applied to water samples collected from polluted lakes.
