Abstract
Adsorption of lead(II) and nickel(II) ions from aqueous solutions was investigated by Bermuda grass biomass. The adsorption process was studied as a function of pH, initial metal concentration, temperature and time. The experimental data obtained were investigated via Langmuir, Freundlich and Temkin isotherms. The kinetic data were examined by pseudo-second-order and intraparticle diffusion models. The biomass was shown to be highly efficient in the removal of lead and nickel ions with the removal of 99% and 54% for lead and nickel ions, respectively. The results showed that Bermuda grass biomass could be utilized as an available, cheap, biodegradable and efficient adsorbent for the removal of toxic metal ions from aqueous solutions.
