| Technologies currently available for the remediation of arsenic-contaminated sites are expensive and environmentally disruptive. Rhizofiltration, a strategy of phytoremediation that uses plants to clean up contaminated water, has been successfully applied in this study to remove arsenic from contaminated water. Proper plant selection is key to ensuring the success of rhizofiltration as a water cleanup strategy. Therefore, the aim of this study was to analyze the behavior of Eleocharis Macrostachya in the removal of arsenic from water. The experiment was performed by duplicate in constructed wetland prototypes. Results indicate that E. Macrostachya was able to tolerate and accumulate in its roots significant amounts of arsenic from water (47mg-kg-1 dry weight). The number of individual plants doubled during the experiment, showing that the presence of the metalloid had no effect on growth. The removal efficiency of arsenic from water in the system ranged from 90 to 99% for an input concentration of 0.1 and 0.5 mg-L-1, respectively. | |
