“…The Infrared spectra of SG-PS-NH 2 and SG-PS-azo-SA are shown in Fig. 1b, and it displayed the presence of vibrational bands characteristic of salicyclic acid group, the peak at 1746 cm -1 was caused by the stretching vibrations of C=O bonds, the peak at 1174 cm -1 by the bending vibrations of ArO-H [12][13][14]. By comparison with the spectrum of SG-PS-NH 2 , the characteristic bands at 1104 cm -1 of asymmetric stretching vibration of Si-O-Si almost disappeared, indicating that composite spheres form bonds with other substances resulting in the relative decrease in the intensity of bands of silica gel.…”

The present study was undertaken to develop a novel adsorbent for heavy metal ions, and this paper presents the synthesis and characterization of a composite material-silica gel microspheres encapsulated by salicyclic acid functionalized polystyrene (SG-PSazo-SA) with a core-shell structure. SG-PS-azo-SA was used to investigate the adsorption of Mn ( , respectively. Thus, silica gel encapsulated by salicyclic acid functionalized polystyrene (SG-PS-azo-SA) is favorable and useful for the removal of Cu(II), Ag(I) and Au(III) metal ions.

“…Salicylic acid has often been chosen in grating on polymeric adsorbents. S. Boussetta et al [12][13] made salicylic acid and their derivatives anchored on poly (styrene-co-divinylbenzene) resin and membrane via a diazo bridge, and found the adsorption capacities of these new materials for iron ions could reach 11.6 mg g -1 and 13.4 mg g -1…”

“…The chelating property of salicylate structure is due to the existence of an OH group in ortho position relative to the carboxyl or carbonyl group that can react with both hard and intermediate cations. Also salicylate moiety has been used as a chelating reagent in the structure of polymeric resins and has been used for metal ion extraction [38][39][40][41][42][43] . Furthermore, salicylic acid was used for functionalization of nanoparticles as a novel adsorbent and used for SPE of some heavy metal ions such as Cu(II), Cd(II), Ni(II) and Cr(III) ions [44] .…”

SbstractThis work describes the synthesis of new ion-imprinted polymers (IIPs) for selective solid phase extraction of Zn(II) ions from aqueous samples. IIPs were synthesized by copolymerization of salicylic acrylate (SA) as a functional monomer and ethylene glycol dimethacrylate (EGDMA) as a crosslinker in the presence of 2,2'-azobisisobutyronitrile (AIBN) as an initiator. The template ions were removed from IIPs particles by leaching with 0.1 M Ethylenediaminetetraacetic acid (EDTA) which leaves cavities in the particles with the capability of selective extraction of the Zn(II) ions. The monomer and the polymer after synthesis have been characterized by 1 H NMR, 13 C NMR and FT-IR studies. The effect of the pH on the extraction efficiency of Zn(II) ions was studied and optimized in pH around 6. The selectivity of the synthesized IIPs was studied in the presence of Co(II), Cd(II) and Ni(II) ions, and the IIPs showed higher affinity for Zn(II) in the presence of other interfering ions.

Atomistic simulations of the structure of highly crosslinked sulfonated poly(styrene-co-divinylbenzene) ion exchange resins

et al. 2015

The microscopic structure of highly crosslinked sulfonated poly(styrene-codivinylbenze) resins have been modeled by generating atomistic microstructures using stochastic-like algorithms that are , subsequently, relaxed using molecular dynamics.Two different generation algorithms have been tested. Relaxation of the microstructures generated by the first algorithm, which is based on a homogeneous construction of the resin, leads to a significant overestimation of the experimental density as well as to an unsatisfactory description of the porosity. In contrast, the generation approach that combines algorithms for the heterogeneous growing and branching of the chains enables the formation of crosslinks with different topologies. In particular, the intrinsic heterogeneity observed in these resins is well reproduced when topological loops, which are defined by two or more crosslinks closing a cycle, are present in their microscopic description. Thus, the apparent density, porosity and pore volume estimated using microstructures with these topological loops, called super-crosslinks, are in very good agreement with experimental measures. Although the backbone dihedral angle distribution of the generated and relaxed models is not influenced by the topology, the number and type of crosslinks affect the medium-and long-range atomic disposition of the backbone atoms and the distribution of the sulfonic groups. Analysis of the distribution of the local density indicates that super-crosslinks are responsible of the heterogeneous homogenization observed during the MD relaxation. Finally, - stacking interactions between aromatic phenyl groups have been analyzed, those in which the two rings adopt a T-shaped disposition being considerably more abundant than those with the rings co-facially oriented, independently of the resin topology.3
