Phytoremediation potential of three leguminous plants towards Chromium

Phytoextraction of Chromium was done by using three leguminous plants Cicer arientum,V. radiata and V. mungo in hydroponic culture. The main objective was to explore the phytoremediation potential of the selected plants. The plants were exposed to a range of concentrations of chromium dichromate from 50 to 750 ppm. The uptake ability of Vigna radiata for chromium increased with the increase of Cr (VI) concentration. Remediation percentage of 51.58% at 750 ppm in Vigna mungo, was observed hence it can be a potential candidate for the removal of Cr. The accumulation of chromium was found to be more in shoot as compared to root and was quite potent in resisting stress caused by Chromium.
