“…In this study the adsorption property of the chelating resin was investigated in the pH range of 1.0-5.6 (experiment showed that further increase of pH resulted in the hydrolysis and precipitation of metal ions). These results are in good agreement with those described by earlier work [8,[10][11][12]14]. At low pH value, hydrogen ion (H + ) reacts with carboxylate ions (COO − ) and tertiary amine (R 3 N) and thus, the chelating resin has low sorption capacity.…”

“…It depends also on the properties of the chelating resin, such as swelling, cross-linking type, cross-linking degree and chelating groups. Chelating resins with different chelating group such as amino, oxime, carbamate, thiols, aminophosphoric and carboxylate have been prepared and illustrated in the literature [5][6][7][8][9][10][11][12][13]. Chelating resins with iminodiacetate group are commercially available, such as Purolite S390, Chelex 100, Amberlite IRC-748 and Lewatit TP 207.…”

New porous chelating resin beads CPN-IDA were prepared by the reaction of poly (acrylonitrile-co-N,N'-methylenebisacrylamide) with etheylenediamine and sodium chloroacetate, respectively. The composition and morphology of the chelating resin was characterized by Fourier transform infrared spectroscopy (FTIR), thermal analysis (TGA and DrTGA), scanning electron microscopy (SEM),surface area measurements by N 2 adsorption (S BET ) and water regain (w%). Batch adsorption experiments were employed to study the impact of some factors that control the adsorption of metal ions including solution pH, concentration of metal ions, contact time and the temperature of the solution. Batch sorption results showed that the chelating resin had high affinity towards Cu(II), Cd(II) and Pb(II). The saturated adsorption capacity at 25 o C was 2.43, 1.93 and 1.45 mmolg −1 resin for Cu(II), Cd(II) and Pb(II), respectively. Among the empirical isotherm models, the equilibrium adsorption results were obviously fitted with Langmuir model. The kinetics was analyzed using pseudo-first-order, pseudo-second-order, and intra-particle diffusion equations. The adsorption kinetic data were well elucidated with pseudo-second-order kinetic model. Thermodynamic parameters were calculated for the uptake of the metal ions under study and it was found to be a spontaneous process. Moreover, the adsorption of metal ions has been studied using column technique. The regeneration of CPN-IDA was experimentally performed by using nitric acid. The chelating resin was used repeatedly for five times with a little decrease in sorption of metal ions.

Poly(hydroxamic acid) ligand was synthesized using ester functionalities of cellulose‐graft‐poly(methyl acrylate) copolymer, and products are characterized by Fourier transform infrared spectroscopy, field emission scanning electron microscopy, high‐resolution transmission electron microscopy, and X‐ray photoelectron spectroscopy analysis. The poly(hydroxamic acid) ligand was utilized for the sensing and removal of transition metal ions form aqueous solutions. The solution pH is found a key factor for the optical detection of metal ions, and the reflectance spectra of the [Cu‐ligand]n+ complex were observed to be the highest absorbance 99.5% at pH 6. With the increase of Cu2+ ion concentration, the reflectance spectra were increased, and a broad peak at 705 nm indicated that the charge transfer (π‐π transition) complex was formed. The adsorption capacity with copper was found to be superior, 320 mg g−1, and adsorption capacities for other transition metal ions were also found to be good such as Fe3+, Mn2+, Co3+, Cr3+, Ni2+, and Zn2+ were 255, 260, 300, 280, 233, and 223 mg g−1, respectively, at pH 6. The experimental data show that all metal ions fitted well with the pseudo‐second‐order rate equation. The sorption results of the transition metal ions onto ligand were well fitted with Langmuir isotherm model (R2 > 0.98), which implies the homogenous and monolayer character of poly(hydroxamic acid) ligand surface. Eleven cycles sorption/desorption process were applied to verify the reusability of this adsorbent. The investigation of sorption and extraction efficiency in each cycle indicated that this new type of adsorbent can be recycled in many cycles with no significant loss in its original detection and removal capability.

“…Various methods, such as chemical precipitation, ion exchange, electrochemical methods, reverse osmosis and adsorption, have been proposed to remove heavy metal ions from water bodies. Among these technologies, the adsorption method using chelating resins has drawn much attention because chelating resins have high adsorption capacity, high efficiency and reusability . Chelating resins can be prepared both through the polymerization of conventional chelating monomers and functionlization modification of polymers.…”

Background Removing toxic heavy metal ions from water bodies is one of the most important areas of water treatment, and using porous membranes with a chelating function is a good route for this. Graft‐type porous membranes with a chelating function are innovate functional membranes. In this work, the main aims are to prepare such a functional membrane and evaluate its adsorption and rejection properties for heavy metal ions in water through adsorption isotherm experiments and permeation experiments. Results Glycidyl methacrylate (GMA) was graft‐polymerized on the surface of polysulfone (PSF) microfiltration membrane through a surface initiating system, getting the grafted membrane PSF‐g‐PGMA. Then the ring‐opening reaction of the epoxy group of the grafted PGMA was carried out with iminodiacetic acid (IDAA) as reagent, obtaining PSF‐g‐PGMA/IDAA membrane, on which a great deal of IDAA as chelating ligand was bonded. PSF‐g‐PGMA/IDAA membrane possesses a strong adsorption ability towards heavy metal ions via the chelating action and electrostatic interaction. The order of adsorption capacity was Pb2+>Cu2+>Cd2+, and the adsorption capacity of Pb2+ ion reached 4.5 µmol cm−2. When an injection filter with a membrane area of 1.77 cm2 was used, the rejection rate of PSF‐g‐PGMA/IDAA membrane for the three heavy metal ions with concentrations of 0.1 mmol L−1 were maintained at a level of 95% until the permeation solution volume reached 100 mL. Conclusion The grafted microfiltration membrane PSF‐g‐PGMA/IDAA can be easily prepared and possesses excellent rejection and removing performance towards heavy metal ions © 2018 Society of Chemical Industry
