“…The ion-exchange study was carried out using three experimental variables such as (a) electrolyte and its ionic strength, (b) uptake time, and (c) pH of the aqueous medium. Among these three variables, two were kept constant and only one was varied at a time to evaluate its effect on metal uptake of the polymer similar to the earlier coworkers [4,19].…”

Terpolymer resin 4-ASAUF was synthesized by the condensation of 4-aminosalicylic acid (4-ASA) and urea (U) with formaldehyde (F) in the presence of 2 N hydrochloric acid. The structure of the resin was characterized by various spectral techniques like infrared (FTIR) and nuclear magnetic resonance (1H and 13C-NMR) spectroscopy. The empirical formula and empirical weight of the resin were determined by elemental analysis. The physiochemical properties of terpolymer resin were determined. The morphological feature of the 4-ASAUF terpolymer resin was studied by scanning electron microscopy (SEM). The chelating ion-exchange property of this copolymer was studied for eight metal ions, namely, Fe3+, Cu2+, Ni2+, Co2+, Hg2+, Zn2+, Cd2+, and Pb2+ ions by using batch equilibrium method. The chelating ion-exchange study was carried out over a wide pH range at different time intervals using different electrolyte of various ionic strengths.

“…Batch equilibrium method was adapted to determine the efficiency of the metal ion uptake capacity of the terpolymer resin under different experimental conditions according to earlier literatures. [16][17][18] Desorption and regeneration studies Exactly, 25 mg of ANAF terpolymer resin was added to 25 ml of 0.1 M metal ion solution in Erlenmeyer flask and mechanically shaked for 1 h. After the shaking time, the resin was filtered off and washed several times with distilled water to remove the excess of metal ion. Then, the resin was treated with 25 ml of 0.01 M NaOH solution in Erlenmeyer flask at the conditions discussed above.…”

An effectual functionalized synthetic resin involving anthranilic acid/4-nitroaniline/formaldehyde was synthesized for the detoxification of hazardous metal ions. The resin was characterized by Fourier transform infrared, 1 H, and 13 C nuclear magnetic resonance spectroscopy, and its morphology was established through scanning electron microscope and X-ray diffraction. The resin was analyzed by thermogravimetric analysis to assess the thermal stability, in which the resin could be used in high temperature aqueous solutions for the elimination of harmful metal ions. The ion-exchange property of the resin was evaluated by batch technique for specific metal ions viz. Fe . The study was extended to three variations such as effect of metal ion uptake in the presence of various electrolytes in different concentrations, effect of pH, and effect of contact time. The outcome proved that the resin can be used as a strong cation-exchanger to remove various metal ions from the solutions. The resin could be regenerated and reused with quantitative recovery of metal ions for few cycles. On comparison with the earlier reported resins, the synthesized resin has found excellent capability of metal ion recovery. The resin possesses an utmost ion-exchange capacity, which is in good harmony with isotherm models and kinetics.

BACKGROUND A novel synthetic terpolymer resin involving anthranilic acid/o‐toluidine/formaldehyde (AOTF) was synthesized for the recovery of harmful and heavy metal ions. The resin was characterized by physico‐chemical, elemental, FTIR, NMR and SEM analysis. Batch separation was used under the following conditions: different concentrations of various electrolytes; variation of pH and time intervals to determine the ion‐exchange properties of the resin for specific metal ions viz. Fe3+, Co2+, Ni2+, Cu2+, Zn2+ and Pb2+. Kinetic and equilibrium studies were also carried out with the terpolymer resin to evaluate the effectiveness of metal ion removal. RESULTS The ion‐exchange capacity for the resin was found to be 5.02 milli mol g−1 indicating that the resin is a more effective ion‐exchanger than some phenolic and polystyrene ion‐exchangers. The amount of Cu2+, Ni2+ and Fe3+ taken up by the resin was 3.12, 2.25 and 2.34 milli mol g−1 at 0.5 mol L−1, respectively, hence the order of metal ion uptake at high concentrations is Cu2+ > Fe3+ > Ni2+. But at lower concentration of 0.01 mol L−1, the uptake of Zn2+ was 2.54, Co2+ was 1.77 and Pb2+ was 0.99 milli mol g−1, respectively, and the order of metal ion uptake is Zn2+ > Co2+ > Pb2+. CONCLUSION The results revealed that the synthesized ion‐exchanger could act as a good ion‐exchanging agent for the removal of toxic and hazardous wastes from industrial effluents. The results are compared with those for some commercial resins and earlier reported resins which indicate that the resin has an excellent capability to remove specific metal ions from waste solutions. © 2014 Society of Chemical Industry
