The selected macrophytes were transferred to the laboratory containing nutrient solution and working Cd standard solutions of different concentrations (1.0, 2.0, 4.0, 8.0 and 16 mg L-1 and harvested at regular time interval of 2, 4, 6, 8 and 10 days. The Cd uptake by these macrophytes showed a linear relationship for S. mucronatus and for R. rotundifolia with the exposure time period (2–10 d). Cd accumulation in the plant parts was higher in the roots for S. mucronatus but reverse in the case of R. rotundifolia and M. intermedium. The maximum bioconcentration factor (BCF) values were found at the 8th day in all the three aquatic macrophytes and translocation factor (TF) was at the 2nd day for S. mucronatus and R. rotundifolia and at the 10th day for M. intermedium respectively. The experimental results demonstrated that these three aquatic macrophytes have a phytoremediation potential for removing Cd from Cd-contaminated water.
