“…The Fourier-transform infrared spectra with the ATR mode (FTIR-ATR) for TP220 before and after the Ni(II) adsorption are shown in Figure 10. The obtained FTIR-ATR spectra of TP220 before the adsorption (pure, without metal ions) show the characteristic bands for the bis(picolylamine) functional groups as well as for the polystyrene matrix which was previously described in the paper by Wołowicz and Hubicki [43], Kołodyńska et al [68], Zagorodni et al [69], Lazar et al [70], Ghosh et al [71], and Traboulsi et al [72]. The spectra confirm the ion exchange resin structure as well as the composition.…”

The development of new, cheaper, and more effective technologies to decrease the amount of wastewater containing heavy metals and to improve the quality is indispensable. Adsorption has become one of the alternative treatment methods. A small number of studies focusing on the batch technique for nickel ion removal by the new generation ion exchangers are described in the literature. In this paper, the Ni(II) removal from aqueous solutions using the ion exchange resins of different types was investigated. The experiments were conducted at different HCl and HCl/HNO3 concentrations, and the initial concentration was 100 mg Ni(II)/L. The investigation of the Ni(II) desorption from the chosen resins were carried out. The Ni(II) removal efficiency and the rate of removal are shown on the kinetic curves and the rate constants as well as kinetic parameters were collected and compared. The isotherm parameters were calculated and Fourier-transform infrared spectroscopy with the attenuated total reflection spectra was performed to determine the nature of adsorption. The experimental results showed that the Ni(II) percentage removal is high and Lewatit MonoPlus TP220 could be an alternative for the treatment of nickel(II) containing wastewaters.

“…The asymmetric stretching of –C–H and –CH 2 were located at 3057, and at 3023 and 2915 cm −1 , respectively. The stretch at 2847 cm −1 is ascribed to the symmetric stretching vibrations of –CH 2 [ 14 , 21 ]. The C N and aromatic skeleton vibrations associated with the pyridine groups were located at 1592 and 1438 cm −1 , while the amine groups in LTP was corroborated by the bands in the region of 988–1159 cm −1 [ 1 , 14 ].…”

“…The functional groups of chelating resins are mainly composed of oxygen, sulfur, nitrogen and phosphorus atoms. [12][13][14] Some studies have investigated the removal of vanadium from solution using chelating resins. Vanadium ions in the form of anions, such as V 3 O − 8 , V 3 O − 7 and VO − 3 , can react with quaternary ammonium in Amberlite IRA-400 chelating resins and N-methyl-D-glucamine in Amberlite IRA-743 chelating resins, reaching the highest vanadium adsorption capacity of 177.7 mg g −1 at a pH of 4.…”

BACKGROUND Acid leaching is an effective method to extract vanadium from polymetallic black shale. However, a large amount of metal impurities, especially iron and aluminum, which accompany V, are released during this process. RESULTS In this study, a aminophosphonic acid chelating resin was used for the differential adsorption and desorption of vanadium, iron and aluminum ions to achieve deep separation and concentration of vanadium ions present in the acid leaching solution of polymetallic black shale. Results showed that vanadium adsorption efficiency reached 90.17% at a pH of 1.8. After differential adsorption and desorption, the V:Fe and V:Al concentration ratios increased from 1.84 to 64.53 and from 0.24 to 37.92, respectively. When a 2.5 mol L−1 NaOH solution was used as desorbent, the separation factors β(V/Fe) and β(V/Al) reached values of 694.22 and 452.29, realizing the selective separation and concentration of vanadium. CONCLUSION It was found that the vanadium, iron and aluminum ions were selectively adsorbed onto the phosphonic acid functional groups (PO(OH)2) and amino functional groups (NH). The vanadium ions existed in the form of the polyvanadate (H2V10O284−), which can be directionally adsorbed onto PO(OH)2 under POH bond cleavage and coordination of H2V10O284− to the unsaturated phosphorus atom and then desorbed through the exchange between hydroxide anions OH− and H2V10O284−. The iron and aluminum ions cannot be desorbed by OH− because the iron and aluminum sulfate moieties FeSO4+ and AlSO4+ were capable of coordinating to the nitrogen atom of the NH group via its lone electron pair. © 2022 Society of Chemical Industry (SCI).
