Biosorption of copper using rice husk

Excessive release of heavy metals into the environment is becoming the important part to be considered. Some of heavy metals widely discharged as ions into wastewater are cadmium,copper,lead,zinc,mercury,and iron.Copper is a common substance that occurs naturally in the environment and spreads throu...
