Biosorption of lead (II) from aqueous solutions by dried water hyacinth (Eichhornia Crassipes)

The contamination of wastewaters, river sediments and soil with toxic metals is a complex problem. The removal of these contaminations has received much attention in recent year using conventional methods such as chemical reduction, ion exchange and electrochemical treatment. The alternative methods...
