Aggiungi Tag | Riassunto: | Artificial floating islands (IFA) are an ecotechnological and innovative alternative, designed for the capture of contaminants present in water bodies. The objective of the research was to evaluate the vetiver (Vetiveria zizanioides) as a possible species for the phytoremediation of water contaminated with excess nutrients. The removal evaluation was analyzed based on four parameters: nitrates (NO3), phosphates (PO4), biochemical oxygen demand (BOD5) and hydrogen potential (pH), every 21 days for a period of three months. By applying the equation of removal of the contaminant load, 96% of PO4 and 4% of NO3 were obtained in the study period. In addition, the simple linear regression mathematical model determined that after 15 days the vetiver began with 0.0004% of NO3 removal and at 16 days with 4.46% of PO4, through the RStudio computer program, which relates time to removal. |
