Phytoremediation, Wastewater, Plant tissue, Nutrient solution, Copper ionAbstract
The present research work has as objective evaluating the copper ion phytoremediation by means of the lentil water species (Lemna minor) in mining wastewater, for this the water with copper ions was prepared at a concentration of 4,780 ppm; having as reference the discharge of an effluent of mining wastewater, the vegetal tissue was in contact with copper for several weeks, then the nutrient solution for the Lemna minor species was prepared, the contact of the plant with the water was carried out with copper ions and the nutrient solution of the plant for 5 weeks, each week the copper in the water analysis was carried out, in the fifth week the copper concentration in the wáter was 1,502 ppm, having a copper removal of 68,57 %. This concludes that Lemna minor species has depurative capacity in mining wastewater.
