Synthetic functionalized terpolymeric resin for the removal of hazardous metal ions: synthesis, characterization and batch separation analysis

Abstract

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.

Polyphenylene sulfide‐based adsorption resins: synthesis, characterization and adsorption performance for Hg(II) and As(V)

“…Ion exchange and adsorption resins have been extensively applied for adsorption, separation, solid phase synthesis, drug delivery, and heterogeneous catalysis [1][2][3][4][5][6] ; their structural design and synthetic optimization have also attracted increasing attention in both academic and technical areas. [7][8][9][10][11][12][13] To the best of our knowledge, the skeleton structure and segment composition of these polymeric materials impose a great influence upon the introduction of chemical functional groups in polymeric network, as well as the chemical activity and osmotic stability of the preceding materials.…”
