“…The latest applications of chelating resins are also presented. Gupta et al [ 30 ] developed a new analytical method for the retention of Pb 2+ from aqueous solutions using the chelated material obtained from the functionalization of Amberlite XAD 2 resin with gallic acid. The operational parameters were optimized and an adsorption capacity of the chelated resin for the retention of Pb 2+ from aqueous solutions was determined to be 4554 µg/g on the tested material.…”

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.

A simultaneous preconcentration and determination procedure for solid phase extraction on AXAD-1180 as 2,6-dimethlmorpholinedithiocarbamate (DMMDTC) chelates and spectrophotometric determinations of Cu (II), Ni (II), and Co (II) in food and environmental samples is proposed in the present work. The effect of some SPE parameters, such as reagent amount, sample pH, eluent type, concentration, and volume, sample and eluent flow rate, and sample volume, on trace metal ion recovery (R%) for the method developed in the standard model solution medium was investigated. Cu(II), Ni(II), and Co(II) retained as DMMDTC complexes on Amberlite XAD-1180 were eluted with 10 mL of 1 M HNO3 (in acetone). Foreign ions were also studied individually on the recovery of trace metal ions using the developed method. Cu(II), Ni(II), and Co(II) ions were preconcentrated and separated from the sample using the developed SPE method, and their concentrations were simultaneously determined using the UV-VIS spectrophotometric method. The spectrophotometric determination was made by measuring the absorbance of colored chelates of metal ions complexed with DMMDTC in a surfactant medium (1% Triton X-100) at wavelengths of 460, 328, and 342 nm for Cu(II), Ni(II), and Co(II), respectively. To test the method's accuracy, certified reference materials (CRM 1204 waste water and TMDA-70.2 Ontario lake water) were analyzed using the proposed method, and metal recoveries were calculated to be between 97.1% and 100.7%. The proposed method worked well with the wheat flour sample. Wheat flour has Cu(II) and Ni(II) contents of 2,16 µgmL− 1 and 0,56 µgmL− 1, respectively.
