A microcosm investigation of fe (iron) removal using macrophytes of ramsar lake: A phytoremediation approach.
The present study deals with the microcosm study of Fe (Iron) phytoremediation using Eichhornia crassipes, Lemna minor, Pistia stratiotes and Salvinia cucullata species collected from the Loktak Lake, a Ramsar Site which exists in north-eastern India (an Indo-Burma hotspot region). Efficiency of these four macrophytes was compared using different Fe concentrations of 1 mg L(-1), 3 mg L(-1) and 5 mg L(-1) for 4 days, 8 days and 12 days, respectively. E. crassipes was the most efficient macrophyte whereas L. minor was the least efficient. E. crassipes removed the highest percentage of Fe, i.e. 89% from 1 mg L(-1), 81.3% from 3 mg L(-1) and 73.2% from 5 mg L(-1) in 12-day experiment.
