Abstract EN
Adsorption of heavy metals on biological sorbents, activated carbon and synthetic resin particles is a common separation technique.
In this study, the biosorption of nickel ions from aqueous solution by palm tree leaves was investigated as a function of shaking time, nickel ions concentration and equilibrium pH.
Competitive adsorption of nickel on palm tree leaves with EDTA and citric acid was also investigated.
Batch adsorption experiments revealed that the biosorption of nickel on palm tree leaves was strongly pH dependent, and maximum nickel sorption was found to occur at equilibrium pH of 6.0.
Dynamics studies showed that : the initial uptake of nickel on palm tree leaves was rapid, equilibrium was established within 30 minutes, and the data followed the pseudo-second order reaction.
The equilibrium sorption data of nickel on palm tree leaves at solution pH 6.0 were described by two-parameter isotherm models such as the Langmuir, Freundlich, and D-R models and three-parameter models such as Redlich-Peterson and Sips isotherm models.
Ion-exchange, adsorption-complexation and intraparticle diffusion mechanisms were found to be involved in the biosorption process.
The Effect of ions interference on the biosorption of nickel on palm tree leaves showed that the sorption of nickel on palm tree leaves was adversely affected by the presence of chelating agents such as EDTA and citric acid.
