RHIZOFILTRATION OF HEAVY METALS (CADMIUM, LEAD AND ZINC) FROM FLY ASH LEACHATES USING WATER HYACINTH (Eichhornia crassipes)
Fly ashes are usually contaminated with toxic heavy metals. These metals are leaching out aftercontact with water during wet disposal system, thus polluting the soil, surface and groundwater. In the present study, a hydroponics experiment was conducted to examine the removalof heavy metals Cd, Pb and Zn by Eichhornia crassipes grown at various concentration of fly ash ranging from 10, 20 and 40...
متن کاملBiosorption and Recovery of Heavy Metals from Aqueous Solutions by Eichhornia Crassipes (water Hyacinth) Ash
Heavy metal’s release without treatment poses a significant threat to the environment. Heavy metals are non-biodegradable and persistent. In the present study the ash of water hyacinth (Eichhornia crassipes), was used to remove six metals from aqueous solutions through biosorption. Results of batch and column experiments showed excellent adsorption capacity. Removal of lead, chromium, zinc, cad...
متن کاملRemoval of Cadmium and Zinc by Water Hyacinth, Eichhornia crassipes
Toxic heavy metal pollution of water and soil is a major environmental problem, and most conventional remediation approaches do not provide acceptable solutions. Wetland plants are being used successfully for the phytoremediation of trace elements in natural and constructed wetlands. This study demonstrates the phytoremediation potential of water hyacinth Eichhornia crassipes, for the removal o...
متن کاملAllelopathic Effects of Water Hyacinth [Eichhornia crassipes]
Eichhornia crassipes (Mart) Solms is an invasive weed known to out-compete native plants and negatively affect microbes including phytoplankton. The spread and population density of E. crassipes will be favored by global warming. The aim here was to identify compounds that underlie the effects on microbes. The entire plant of E. crassipes was collected from El Zomor canal, River Nile (Egypt), w...
