“…Therefore, Cr(III) ions have low toxicity due to their limited bio-availability and solubility. In contrast, the high solubility and bio-availability of Cr(VI) anions make it a particular environmental concern [28][29][30][31][32][33][34][35].…”

“…26 For example, the sorption capacity toward Cu(II) ions decreased in order: PGME-deta > PGME-en > PGMEteta (Note: additional marks -en, -deta, and -teta stand for PGME with attached ethylene diamine, diethylene triamine, and triethylene tetramine, respectively). In earlier works, [27][28][29] the sorption rate and the sorption capacity of amino-functionalized macroporous crosslinked copolymers based on glycidyl methacrylate (GMA) for different metal ions have been investigated. We have successfully used PGME functionalized with diethylene triamine for the removal of Cr(VI) anionic species from acidic solutions.…”

ABSTRACT:The possibility of sorption of technetium-99 in the form of pertechnetate anion (TcO 4 À ) and the sorption kinetics for removing TcO 4 À from aqueous solution by chelating polymers based on glycidyl methacrylate (GMA) were investigated. Two samples of macroporous crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME), with different amount of the crosslinker (ethylene glycol dimethacrylate, EGDMA), were synthesized by suspension copolymerization and functionalized with diethylene triamine (deta). We propose that nonspecific sorption of pertechnetate anion via electrostatic interactions takes place at the protonated amino groups of macroporous crosslinked copolymer. The results of batch experiments performed at pH 1-14 showed fast sorption kinetics for removing TcO 4À by amino-functionalized PGME-deta in a wide range of pH, that is, from 1.0 to 9.0. Almost complete removal of TcO 4 À (91-98%) was reached within 180 min in the stated pH range (1.0-9.0), with the sorption half-times of under 25 min. The partitioning coefficients of linear adsorption isotherms, with 180-min equilibrium time, reach the high values of 2130 mL g À1 and 1698 mL g À1 for the two samples of synthesized PGME-deta.

“…The pseudo-second-order model was determined to best fit with adsorption data meaning that adsorption depends both on the properties of the metal and the adsorbent. Nastasovic et al [36] have also functionalised macroporous poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) (PGME) by reacting the pendant epoxy groups with diethylene triamine (PGME-10/12-DETA) and investigated the adsorption mechanism of the adsorbent towards Cu(II), Cd(II) and Pb(II) ions in aqueous solution. The FTIR, X-ray photoelectron spectroscopy (XPS), SEM-EDX and atomic force microscopy (AFM) were used to elucidate the adsorption mechanism before and after interaction of PGME-10/12-DETA with the target ions.…”

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.
