“…Yayayürük et al [33] have used the same adsorbent, for the first time, for the selective preconcentration of Hg(II) prior to cold-vapour atomic-fluorescence measurements, and separate determinations of Hg(II) and MeHg(I) at the trace level were performed at a ng L −1 level. In addition, adsorption isotherms were studied, and the affinity of the adsorbent to several metal ions, such as Pb(II), Zn(II), Cu(II), Cd(II) and Fe(III), was investigated.…”

Heavy metals are not biodegradable and tend to accumulate in living organisms. Many heavy metal ions are known to be toxic or carcinogenic. Thus, removal of these toxic heavy metals from water is of crucial importance to protect the human population and the environment. In recent years, polymeric adsorbents have received considerable interest for heavy metal removal mainly due to important technological and scientific developments such as easy synthesis at controlled dimensions with variable functional groups, perfect mechanical rigidity, tunable surface chemistry, large surface area, pore size distribution, high uptake values and feasible regeneration under mild conditions. This chapter has attempted to present to the readers the widespread investigations of acrylic-based polymeric adsorbents so that the reader can get an idea about the various types and forms of polymeric materials used for the removal of heavy metals from water.

“…Moreover, in order to identify the selectivity of Cu(II) with respect to competitor ions (Al, Ba, Co, Mn, Mg, and Ni), the distribution and the selectivity coefficients of Cu(II) were obtained from equilibrium binding data using the equations given in a previous study (Yayayürük et al 2011). …”

A macroporous glycidyl methacrylate (GMA)-methylmethacrylate (MMA)-divinyl benzene ( D V B ) t e r p o l y m e r f u n c t i o n a l i z e d w i t h diethylenetriamine tetraacetic acid (DTTA) (GMA-MMA-DVB-DTTA) sorbent was successfully applied for the uptake of Cu(II) from the aqueous solutions. Adsorption characteristics for copper ion were investigated by a batch sorption in under different experimental conditions, and the optimum parameters for the quantitative sorption of Cu(II) ion were found to be as follows: pH of 7.0, a contact time of 30.0 min, and a sorbent amount/solution volume ratio of 1.5 mg/mL. The quantitative elution from the sorbent was performed with 1.0 M HCl (>95 %). Among three kinetic models, the pseudo-second-order kinetic model provides the best correlation for the process. The nonlinear resolution of the Langmuir isotherm equation has been found to show the closest fit to the equilibrium data. The results indicates that the presence of the competitor ions (Al, Ba, Co, Mn, Mg, and Ni) has no obvious influence on the sorption of Cu(II) ion under the optimum conditions and the polymeric sorbent has a good selectivity for the sorption of Cu(II) ions with a sorption percent of ≥99 %. Sorption/desorption studies were performed for ultrapure, tap, bottled drinking and industrial wastewater samples, and it is examined that the proposed method has been successfully applied to the real samples for the removal of Cu(II) acceptable accuracy and precision. The results of this work indicated that the polymeric sorbent could be a simple and suitable method for the effective removal of Cu(II) ions from waters.
