Biosorption 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 کاملAdsorption of Congo Red Dye from Aqueous Solutions Using Roots of Eichhornia Crassipes: Kinetic and Equilibrium Studies
Adsorption of Congo red (CR) from aqueous solution using dried roots of Eichhornia crassipes was studied. Batch experiments were carried out for sorption kinetics and isotherms. Experimental results obtained showed that adsorption process was highly dependent on contact time, adsorbent dosage, initial dye concentration and particle size. The sorption equilibrium for Congo red dye by E. crassipe...
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...
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 کاملMethane Production by Anaerobic Digestion of Water Hyacinth (eichhornia Crassipes)
Water hyacinth (Eichhornia crassipes) is an aquatic biomass species that exhibits prolific growth in many s s o f h e world (1). It has been suggested as a strong candidate for production of methane because of high biomass yield potential (2). Several studies have been carried out which establish that methane can be produced from water hyacinth under anaerobic digestion conditions (3-6). Both b...
