Nitrogen Phytoremediation by Water Hyacinth (Eichhornia crassipes (Mart.) Solms)
The phytoremediation potential of water hyacinth, Eichhornia crassipes (Mart.) Solms, was examined in two independent studies under nitrogen (N) rates of 0, 40, 80, 100, 150, 200, and 300 ppm. A modified Hoagland solution was added to ponds containing water hyacinths which were rated and measured weekly for 4 weeks. The hyacinths accounted for 60–85% of the N removed from solution. Net producti...
متن کاملHeavy Metal Phytoremediation by Water Hyacinth at Constructed Wetlands in Taiwan
The ability of water hyacinth ( Eichhornia crassipes Mart. Solms.) to absorb and translocate cadmium (Cd), lead (Pb), copper (Cu), zinc (Zn), and nickel (Ni) was studied in the Erh-Chung wetlands. Translocation ability was defined as the quantity of Cu, Pb, Cd, Ni, and Zn translocated in the plant’s tissues, and was expressed as a root/shoot ratio. The ratio results were in the order of Cu>Pb>C...
متن کاملThe Effect of pH on Simultaneous Saccharification and Fermentation Process of Water Hyacinth (Eichhornia crassipes (Mart.) Solms.) Using Trichoderma harzianum and Saccharomyces cerevisiae
Research has been done on simultaneous saccharification and fermentation of water hyacinth (Eichhornia crassipes (Mart.) Solms.) with different pH to produce bioethanol. Simultaneous saccharification and fermentation process was the integration between saccharification or hydrolysis of cellulose into sugar and fermentation of sugar into ethanol, with utilized microorganism of Trichoderma harzia...
متن کاملEvaluation of Cadmium Removal from the Water in Phytoremeiation Process Using Eichhornia crassipes
Conserving water resources and protecting them from pollution are of high account in the natural cycle of our life. This study has tried to determine the refining potential and capacity of water hyacinth (Eichhornia crassipes) in order to remove the cadmium from water, studying the influence of factors such as initial concentration of cadmium, contact time, absorbent mass, and pH. Results have ...
متن کاملNew record of Eichhornia crassipes (Water Hyacinth) from north of Iran
In October 2012, in a survey in order to study the flora of paddy fields and aquatic ecosystems of Gilan province (N Iran), we encountered an unknown species in “Aynak lagoon” in southeast of Rasht, covered surface of about 12 ha pond densely. Comparing the flora of pond with previous years or adjacent ponds showed that, the new weed was dominant in interference with natural flora of aquatic ec...
