“…Chelating resins have attracted interest over time due to their high selectivity in metal removal compared to conventional cation exchangers [ 21 , 22 , 23 ]. In addition, they offer a variety of advantages such as low operating costs, and ease of operation and they do not generate chemical sludge as do the conventional methods previously presented.…”

In the present study, two chelating resins were prepared and used for simultaneous adsorption of toxic metal ions, i.e., Cr3+, Mn2+, Fe3+, Co2+, Ni2+, Cu2+, Zn2+, Cd2+, and Pb2+ (MX+). In the first step, chelating resins were prepared starting with styrene-divinylbenzene resin, a strong basic anion exchanger Amberlite IRA 402(Cl−) with two chelating agents, i.e., tartrazine (TAR) and amido black 10B (AB 10B). Key parameters such as contact time, pH, initial concentration, and stability were evaluated for the obtained chelating resins (IRA 402/TAR and IRA 402/AB 10B). The obtained chelating resins show excellent stability in 2M HCl, 2M NaOH, and also in ethanol (EtOH) medium. The stability of the chelating resins decreased when the combined mixture (2M HCl:EtOH = 2:1) was added. The above-mentioned aspect was more evident for IRA 402/TAR compared to IRA 402/AB 10B. Taking into account the higher stability of the IRA 402/TAR and IRA 402/AB 10B resins, in a second step, adsorption studies were carried out on complex acid effluents polluted with MX+. The adsorption of MX+ from an acidic aqueous medium on the chelating resins was evaluated using the ICP-MS method. The following affinity series under competitive analysis for IRA 402/TAR was obtained: Fe3+(44 µg/g) > Ni2+(39.8 µg/g) > Cd2+(34 µg/g) > Cr3+(33.2 µg/g) > Pb2+(32.7 µg/g) > Cu2+ (32.5 µg/g) > Mn2+(31 µg/g) > Co2+(29 µg/g) > Zn2+ (27.5 µg/g). While for IRA 402/AB 10B, the following behavior was observed: Fe3+(58 µg/g) > Ni2+(43.5 µg/g) > Cd2+(43 µg/g) > Cu2+(38 µg/g) > Cr3+(35 µg/g) > Pb2+(34.5 µg/g) > Co2+(32.8 µg/g) > Mn2+(33 µg/g) > Zn2+(32 µg/g), consistent with the decreasing affinity of MX+ for chelate resin. The chelating resins were characterized using TG, FTIR, and SEM analysis. The obtained results showed that the chelating resins prepared have promising potential for wastewater treatment in the context of the circular economy approach.

Sulfonated mesoporous polydivinylbenzene solid acid was prepared by in situ sulfonation method, and the physical chemical properties of this solid acid was characterized by XRD, BET, FT‐IR, etc. Acid density of sulfonated mesoporous polydivinylbenzene was characterized by acid base titration, and the result showed that the acid density was 1.58 mmol H+/g. The condensation of phenol and acetone was used as a probe reaction to investigate the catalytic performance of sulfonated mesoporous polydivinylbenzene as a solid acid. Results showed that the phenol conversion rate could approach theoretical conversion rate with Bisphenol‐A selectivity of 91 % at 90 °C. More importantly, sulfonated mesoporous polydivinylbenzene had good stability, and after repeated use for five times, the catalytic performance was not significantly reduced.
