Isothermal Equilibrium and Kinetic Study on the Adsorption of Copper (II) Ions by Dried Water Hyacinth Biomass (Eichhornia crassipes)

This study dealt with the determination of copper (Cu2+) ion adsorption capacity of dried roots and above ground vegetative structure of Eichhornia crassipes taken from Lake Palacpacquen in San Pablo, Laguna. Both the adsorption by roots and aerial portion fitted the Langmuir and Freundlich models suggesting that the biosorption mechanism is complex.
