“…Among the electrolytes such as NaNO 3 , NaCl, NaClO 4 and Na 2 SO 4 , the NaNO 3 are found to be more suitable electrolyte supporting to the ion exchange of metal ion under study by HBTE-II resin. Trivalent metal ion shows comparatively higher rates of metal uptake than divalent.…”

“…The amount of metal exchanged was determined from the difference between reading in blank and actual experiments [9][10][11] . The amounts of metal ion in mg per g of resin were calculated in the presence of NaCl, NaNO 3 , NaClO 4 and Na 2 SO 4 electrolyte for metal ions Sb 3+ , Bi 3+ , Zn 2+ and Mg 2+ .…”

“…The inspection of the data reveals that the amount of metal ions taken up in the presence of NaNO 3 is larger than NaCl, Na 2 SO 4 and NaClO 4 . For the metal ions Sb 3+ , Bi 3+ , Mg 2+ and Zn 2+ , the exchange capacity Wavelength, nm Absorbance increases with increases in the concentration of NO 3 -, ClO 4 -and Cl -, whereas it decreases with increases in concentration of SO 4 2-. This is due to the fact that metal ions under study form kinetically more inert compound with respect to SO 4 2-as compared to metal-resin interaction.…”

Ion-exchange resin (HBTE-II) was synthesized by polycondensation in the presence of polyphosphoric acid as a catalyst using monomers p-hydroxybenzaldehyde (0.2 M), thiourea (0.1 M) and ethylene glycol (0.4 M) at 120 0 C. The terpolymer resin was characterized by elemental analysis, the number average molecular weight, UV-Visible, IR and 1 H NMR spectrum. Chelating ion-exchange properties of this copolymer were studied for Bi 3+ , Sb 3+ , Zn 2+ and Mg 2+ ions. A batch equilibrium method was employed in the study of the selectivity of metal ion uptake involving the measurements of the distribution of a given metal ion between the polymer sample and a solution containing the metal ion. The study was carried out over a wide pH range and in media of various ionic strengths. The metal ions were estimated spectrophotometrically. The HBTE-II terpolymer resin was found to be selective chelating ion-exchange resin for Sb 3+ , Bi 3+ and Zn 2+.

8-Hydroxyquinoline-5-sulfonic acid-thiourea-formaldehyde copolymer resins were synthesized through the condensation of 8-hydroxyquinoline-5-sulfonic acid and thiourea with formaldehyde in the presence of hydrochloric acid as a catalyst and with various molar ratios of the reacting monomers. The resulting copolymers were characterized with UV-visible, IR and 1H-NMR spectral data, employed to determine the reactivity of monomers. The average molecular weights of these resins were determined with vapor pressure osmometry and conductometric titration in a nonaqueous medium. The chelation ion-exchange properties were also studied with the batch equilibrium method. The resins were proved to be selective chelating ion-exchange copolymers for certain metals. The chelation ion-exchange properties of these copolymers were studied for Cu 2þ , Ni 2þ , Co 2þ , Pb 2þ , and Fe 3þ ions. The study was carried out over a wide pH range and in media of various ionic strengths. The copolymers showed a higher selectivity for Fe 3þ ions than for Cu 2þ , Ni 2þ , Co 2þ , and Pb 2þ ions.

Terpolymer resins (2,4-DHBPOF) were synthesized by the condensation of 2,4-dihydroxybenzophenone and oxamide with formaldehyde in the presence of acid catalyst and using varied molar ratios of reacting monomers. Terpolymer resins composition has been determined on the basis of elemental analysis and the number average molecular weight of these resins was determined by conductometric titration in nonaqueous medium. Viscometric measurements in N,N-dimethyl formamide have been carried out with view to ascertain the characteristic functions and constants.UV-visible, IR and NMR spectra were studied to elucidate the structure. The ion-exchange study of the prepared resin was checked by batch equilibrium method with selected metal ions, Cu
