| Arsenic (As) retention in constructed wetlands (CW) is highly influenced by the physicochemical conditions of the environment, which usually manifests as a redox potential (Eh) variation in the system which also depends on the pH and water temperature. This study analyzes the influence of Eh and pH on As removal in a CW mesocosms. The study was conducted with three CW prototypes. Two prototypes were planted with Eleocharis macrostachya and Schoenoplectus americanus (CWA and CWB respectively), while another one remained unplanted as a control (CWC). The CW prototype system operated in parallel for 338 days. It was nourished using synthetic water prepared with ground water and NaAsO2 at a concentration of 90.66 ± 14.95 μg/L. The theoretical retention time was two days. The parameters monitored during the experiment were: Eh, pH, CW temperature and room temperature, and As inflow and outflow. | |
