Heavy metals removal in animal wastewater using water hyacinths (Eichhornia crassipes)

Animal wastewaters contain heavy metals which were due to their presence in animal’s diet. This study was conducted to observe the uptake of a mixture of heavy metals such as copper (Cu), cadmium (Cd), lead (Pb) and zinc (Zn) by water hyacinths for a period of four days and leaching of heavy metals...

This study was conducted to observe the uptake of a mixture of heavy metals such as copper (Cu), cadmium (Cd), lead (Pb) and zinc (Zn) by water hyacinths for a period of four days and leaching of heavy metals in treated and untreated wastewater using living and dead water hyacinths for a period of 7 days.
