AB  - Silver as one of the most known precious metal is used on a large scale in various industrial
branches and the release of silver ions from such industrial activities potentially can cause
serious environmental problems. Therefore, the removal of this metal from wastewater is a great
challenge, and it is crucial for the quality improvement of the environment. Porous polymer
materials with high specific surface areas and other specific physical and chemical
characteristics have gained much attention as sorbents in the field of environmental protection.
In this paper, macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)
copolymer synthesized by suspension copolymerization and functionalized with
diethylenetriamine was employed for silver ions sorption from aqueous solution at unadjucted
pH and room temperature. The sorption kinetics and isotherms were studied to establish the
mechanisms of sorption process. The kinetic data were modeled with pseudo-first-order (PFO),
pseudo-second-order (PSO), Elovich and fractional power (FP) models as well as intraparticle
diffusion (IPD) and liquid diffusion model (LFD), while the equilibrium data were analized
using Langmuir, Freundlich, Sips and Redlich-Peterson isotherm models. Eight error functions
such as coefficient of determination (R2
), Marquardt’s percent standard deviation (MPSD), Chisquare statistic test (χ2
), hybrid fractional error function (HYBRID), the root mean square error
(RMSE), the sum of the errors squared (SSE), sum of the absolute errors (SAE), and average
relative error (ARE) were used to estimate the error deviations between theoretically predicted
and experimental values of sorption capacities. The best kinetic and isotherm models were
determined by normalizing eight error functions and finding the sum of normalized error value
(SNE). The sorption kinetic studies revealed that the sorption of silver by macroporous aminofunctionalized sorbent obeys the PSO kinetic model. In addition, the results indicate that
sorption was governed by intraparticle diffusion with the evident influence of liquid film
diffusion. The obtained results showed that the sorption isotherm data were satisfactorily fitted
to the Redlich-Peterson isotherm model.
