“…This agglomeration and spherical nature were originated from the water content (less viscous), initiator type and intraparticle bonds of the AN-AA monomers. Aguilar and coworkers reported same morphologies for synthesized acrylonitrile/ethylene glycol dimethacrylate cross linked adsorbents [32]. The measured mean particle diameter (using ImageJ™ software, 1.52a version) revealed a slight change in poly(AN- co -AA) beads to 308 nm from 300 nm after chemical modification.…”

The paper evaluates the adsorptive potential of thiourea-modified poly(acrylonitrile-co-acrylic acid), (TA-poly(AN-co-AA)) for the uptake of cationic methylene blue (MB) from aquatic environments via a batch system. TA-poly(AN-co-AA) polymer was synthesized through redox polymerization and modified with thiourea (TA) where thioamide groups were introduced to the surface. Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM), CHNS and Zetasizer were used to characterize the physico-chemical and morphological properties of prepared TA-poly(AN-co-AA). Afterwards, it was confirmed that incorporation of thioamide groups was successful. The adsorption kinetics and equilibrium adsorption data were best described, respectively, by a pseudo-second-order model and Freundlich model. Thermodynamic analysis showed the exothermic and spontaneous nature of MB uptake by TA-poly(AN-co-AA). The developed TA-poly(AN-co-AA) polymer demonstrated efficient separation of MB dye from the aqueous solution and maintained maximum adsorption capacity after five regeneration cycles. The findings of this study suggested that synthesized TA-poly(AN-co-AA) can be applied successfully to remove cationic dyes from aquatic environments.

“…Polymeric materials typically crosslinked with DVB produced a hydrophobic backbone where interactions with analyte molecules are strictly through π-π interactions [30]. DVB is known as a rigid crosslinker due to its aromatic group that prevents the packing of polymeric chains [31]. Introduction of long, flexible EGDMA into the polymer system provides greater flexibility and spacing between the polymer chains which favor the accessibility and attachments of analyte molecules to the functional groups of EGDMA [32].…”

“…Introduction of long, flexible EGDMA into the polymer system provides greater flexibility and spacing between the polymer chains which favor the accessibility and attachments of analyte molecules to the functional groups of EGDMA [32]. In addition, the hydrophilic and polar character of EGDMA allows a high affinity to the aqueous phase and does not exhibit steric constraints when it is used as an adsorbent [31].…”

Ethylene glycol dimethacrylate (EGDMA) is used as a crosslinker in poly(acrylonitrile (AN)-co-vinylbenzyl chloride (VBC)) to investigate the effect of long-chain crosslinker to the porosity of the terpolymer system. Poly(AN-co-EGDMA-co-VBC) is synthesized by using precipitation polymerization method and further hypercrosslinked by Friedel-Crafts reaction. FT-IR spectra of poly(AN-co-EGDMA-co-VBC) show that the absorption bands at ~1290 cm−1 that are assigned to the C–Cl vibrations are almost disappeared in hypercrosslinked (HXL) poly(AN-co-EGDMA-co-VBC) polymers, confirming that the hypercrosslinking reaction is successful. SEM images show that the morphologies of the polymers are retained through the hypercrosslinking reactions. Brunauer–Emmett–Teller (BET) analysis shows that hypercrosslinked polymers had a specific surface area up to 59 m2·g−1. The preliminary performance of the terpolymer adsorbent to capture polar analyte is evaluated by adsorbing salicylic acid and mefenamic acid from aqueous solution in a batch system. The maximum adsorption capacity of salicylic acid and mefenamic acid were up to 416.7 mg·g−1 and 625 mg·g−1, respectively, and the adsorption kinetic data obeyed pseudo-second-order rate equation.

“…Recently, porous polymeric adsorbents synthesized for phenol removal have attracted significant attention due to feasible regeneration for repeated use, a perfect skeleton strength, physicochemical properties, and their high surface area [1]. Also, a high adsorption capacity for the removal of phenol and substituted phenols was found in the porous polymeric adsorbents [1,4,[22][23][24][25][26][27][28][29][30]. Among these porous polymeric adsorbents, it is expected that polymer beads have a large adsorption capacity for inorganic/…”

This paper reports synthesis of the poly(ethylene glycol dimethacrylate-n-vinyl imidazole) ([poly(EGDMA-VIM)]) microspheres by suspension polymerization for the removal of phenol from an aqueous solution. The synthesized [poly(EGDMA-VIM)] microspheres were characterized by various analysis techniques. The [poly(EGDMA-VIM)] microspheres possessed a high specific surface area (304.4 m 2 g −1). It was found that the pseudo-second-order kinetic and Freundlich isotherm models could well define the phenol adsorption process. The maximum capacity of the [poly(EGD-MA-VIM)] microspheres was calculated to be 34.7441 mg g −1 at 298 K and natural pH from Langmuir isotherm. The adsorption thermodynamics revealed that the adsorption of phenol was an exothermic and spontaneous process. The [poly(EGDMA-VIM)] microspheres were easily regenerated by using a 0.01 M NaOH solution, and were repeatedly used for at least 5 cycles without losing the adsorption capacity. The experimental results suggest that the [poly(EGDMA-VIM)]microspheres can be implemented as a promising adsorbent for phenol removal from wastewater.
