 abstract = {Ion-exchange is an alternative process for uptake of heavy metals from
aqueous solutions. In the present study, the sorption of nickel(II)
ions from aqueous solution was investigated by using Lewatit MonoPlus
SP 112 (strongly acidic, macroporous cation-exchange resin) in a batch
adsorption system as a function of pH (2.0-8.0), initial nickel
concentration (50-200 mg/L), resin dosage (0.5-2.0 g/L), contact time
(0.5-3h), and temperatures (298-318K). The data were analyzed on the
basis of Lagergren pseudo-first order, pseudo-second order (Types 1-5),
Elovich and external, Weber-Morris intraparticle, pore-surface mass
diffusion models. The experimental data showed that the maximum pH for
efficient sorption of nickel(II) was 6.0. At the optimal conditions,
nickel(II) ions sorption on the resin was decreased when the initial
metal concentration increased. The results indicated that the resin
dosage strongly affected the amount of nickel(H) ions removed from
aqueous solution. The adsorption process was very fast due to 80% of
nickel(II) sorption was occurred within 30 min and equilibrium was
reached at about 90 min, Freundlich and Langmuir adsorption isotherm
models were used for sorption equilibrium data and the maximum
adsorption capacity (171 mg/g) of Lewatit MonoPlus SP 112 was obtained
from Langmuir isotherm. The thermodynamic parameters (Delta G degrees,
free energy change; Delta S degrees, enthalpy change; and Delta H
degrees, entropy change) for sorption of nickel(II) ions were
evaluated. The rise in temperature caused a partly increase in the
value of the equilibrium constant (K-c) for the sorption of nickel(II)
ions. Moreover, column flow adsorption study was also studied.
Breakthrough curves were obtained from column flow studies by using
both synthetic solution and rinsing bath water of filter industry. The
column regeneration was carried out for two sorption-desorption cycles.
The eluant used for regeneration of the cation-exchange resin was 7%
(w/w) HCl. The experimental results demonstrated that Lewatit MonoPlus
SP 112 cation-exchange resin could be used effectively for the removal
of nickel(II) ions from aqueous medium. (C) 2009 Elsevier B.V. All
