Resumen o descripción
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.
