Abstract
The biosorption of Cu(II) and Zn(II) ions from aqueous solution by raw water hyacinth (RWH) and acid treated water hyacinth (TWH) was studied as a function of time, biosorbent dosage and pH. The kinetic results obeyed well the pseudo second-order model. Maximum biosorption capacities for RWH and TWH were measured as 0.49, 6.56 mg/g for Cu(II) and 2.66, 10.71 mg/g for Zn(II), respectively. FT-IR analysis indicated that carboxyl groups in water hyacinth may be involved in the mechanism of Cu(II) and Zn(II) adsorption.
