A microcosm investigation of fe (iron) removal using macrophytes of ramsar lake: A phytoremediation approach

摘要

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.
