(cest2017_00055) Potential of Azolla pinnata for removal of cadmium from wastewater by phytoremediation

摘要

In this study, Azolla pinnata is a free- floating plant was obtained from Agric. Microbial Dept., Soils, Water and Environment Research Institute (SWERI), Agric. Res. Center (ARC), Giza, Egypt and used to investigate its bioindicative value by evaluating its ability to accumulate different concentrations of Cd+2 (0, 0.1, 0.2, 0.3, 0.4 and 0.5 ppm) in the form of Cd (NO3)2.4H2O. The effect of different concentrations of Cd+2 on biomass production of this plant, doubling time and metal accumulation was studied. In such concern, growth of A. pinnata was determined during 25 days of incubation under greenhouse conditions. From the results of this study, it can be concluded that A. pinnata could be used as a reliable way for biomonitoring of cadmium and in pollution assessment. Overall, A. pinnata is an effective, eco-friendly and low-cost treatment technology.
