Bioremediation of Wastewater Enriched with Cd, Cr and Pb Using Floating Macrophytes

This study aimed to explore the effectiveness potential of Eichhornia crassipes, Pistia stratiotes and Salvinia molesta for reduction potentially toxic metals from effluents enriched with Cd, Cr Pb. Based on a 21-day laboratory-scale experiment, total three concentrations at 1, 5 10 mg/L were selected culture each macrophytes. In addition, kinetics prediction models used analyze metal data understand behavior removal rate species Taguchi methodology see what right conditions greater efficiency are. The results suggested that macrophytes was able reduce crassipes manages 90.8-99.99% 90.8-99.9% 89.6-99.9% Pb, 74.6-99.9% 91.2-99.9% Pb 83.2-99.9% 62.2-99.9% 89.2-99% first-order model it is adjusted appropriately plants, having an adjustment R2 than 0.80. analysis shows optimal phytoremediation occur 1 after 21 days.
