This work aims the study of the ability of Phragmites australis roots to accumulate and transfer metals such as iron and zinc present in water filled with discharges from industrial sources. We are interested in the movement and distribution of these metals in the roots through a lagoon system designed for vertical flow in the laboratory through two trays where treatment plants Phragmites australis were planted. The results showed the presence of high concentrations of metals such as iron and zinc concentrates in the roots. After purification, the concentrations of these metals are highly decreased, confirming the effectiveness of the system.
