Abstract
The present investigation deals with the decontamination of arsenic contaminated water using phytoremediation technique. Three macrophytes Azolla pinnata, Lemna minor and Hydrilla verticillata were exposed to 1.0 ppm of an arsenic salt (sodium arsenite) separately as well as in combination (mixed in equal proportion) of macrophytes (A:L:H) for 10 days. The concentration of arsenic in control (wild) macrophytes was below detectable limit. Following exposure the concentration of arsenic increased steadily in all the plants and after 10 days the efficacy of arsenic depletion in phytoremediated media was in the order: A. pinnata>Mixed plants (A: L: H)>L. minor>H. verticillata. It was found that A. pinnata detoxify the arsenic contaminated water most efficiently.
