Abstract
:
In this study the natural palm fiber and modified palm fiber by zinc oxide nanoparticle was synthesized and used for the removal of lead ions as example of an inorganic pollutants in water. The removal efficiency increased using modified sorbent rather than non-modified sorbent. During the application of linear equations of isotherm to describe the sorption equilibrium the maximum sorbed amount detected and the percentage removal of lead ions using 0.1 g of natural sorbent and 0.1 g of modified sorbent at room temperature and 30 min contact time were 86.99 % and 99.45 % respectively. The kinetics model proved that lead ion sorption following pseudo-second-order. The thermodynamic study proved the sorption of lead ions spontaneous due to the negative value of ∆G and random in nature due to the negative value of ∆S and the process is exothermic due to amount adsorbed decrease with increasing of temperature and also the ∆H value was negative. The sorption process of lead ion onto modified and non-modified sorbent was due to electrostatic attraction between positive ions of lead and negative ions on the active sites of sorbent surface.
