摘要：Phragmites australis was cultured in Ba and Sr contaminated solutions for 2 weeks to investigate its potential to remove these metals. With the increase of time, the levels of metals in reeds increased. The more metals in solutions, the more metals entered the root system. After 2 weeks, 15.01±1.71 mg/g Ba and 3.93±0.05 mg/g Sr were sequestered in roots from solutions with 80 mg/L Ba and 20 mg/L Sr. Metals in shoots were slightly enhanced with the increase of metals in solutions. The translocation factor (TF) of Ba was not changed with time while the TF of Sr increased. The TF of Ba and Sr were less than 1 which further indicated that roots were the main organs for metal storage. Reed may be used to clean Ba and Sr contaminated water. Further in situ studies are needed to confirm the feasibility.
