“…However, for a less concentrated solution, the separation proves to be problematic. Lewatit TP 208 was chosen as a promising ion exchange resin because its iminodiacetic acid groups exhibit good selectivity for trivalent indium over the divalent cations (Fe, Zn) [20][21][22].…”

Indium separation using ion exchange resins from acidic polymetallic and very diluted solutions are investigated. Since the selectivity of commercial ion exchange resins have proven to be too low for an effective separation from solutions with high content of other metals, Lewatit® TP 208 was impregnated with common extractants to enhance its properties. By resin impregnation with D2EHPA and Cyanex 272, not only the selective indium recovery was reached but also the resin capacity was increased approx. two times. The best loading and elution performance were shown by Cyanex 272‐impregnated Lewatit® TP 208, increasing the indium purity in the eluate from 0.75 % to 85 %.

“…Different estimations indicate that into the Earth’s crust indium content ranges from 50 to 200 parts per billion [ 8 ]. However, at the present consumption rate indium reserves are expected to be depleted in 20 years, and the demand and consumption of indium increases every year [ 9 , 10 ]. Until now, different attempts were made for In recovery from different scraps [ 7 ].…”

Indium and its compounds have many industrial applications and are widely used in the manufacture of liquid crystal displays, semiconductors, low temperature soldering, and infrared photodetectors. Indium does not have its own minerals in the Earth’s crust, and most commonly, indium is associated with the ores of zinc, lead, copper and tin. Therefore, it must be recovered as a by-product from other metallurgical processes or from secondary raw materials. The aim of this study is to investigate the adsorption properties for recovering indium from aqueous solutions using iron–magnesium composite (MgFe2O4). In addition, the results show that the material offers very efficient desorption in 15% HCl solution, being used for 10 adsorption–desorption cycle test. These results provide a simple and effective process for recovering indium. Present study was focuses on the synthesis and characterization of the material by physico-chemical methods such as: X-ray diffraction, FT-IR spectroscopy, followed by the adsorption tests. The XRD indicates that the MgFe2O4 phase was obtained, and the crystallite size was about 8 nm. New prepared adsorbent materials have a point of zero charge of 9.2. Studies have been performed to determine the influence of pH, initial indium solution concentration, material/solution contact time and temperature on the adsorption capacity of the material. Adsorption mechanism was established by kinetic, thermodynamic and equilibrium studies. At equilibrium a maximum adsorption capacity of 46.4 mg/g has been obtained. From kinetic and thermodynamic studies was proved that the studied adsorption process is homogeneous, spontaneous, endothermic and temperature dependent. Based on Weber and Morris model, we can conclude that the In (III) ions takes place at the MgFe2O4/In (III) solution–material interface.

“…Industrial wastewater containing toxic ions are directly or indirectly discharged into the water resources mainly in the developing countries. Various techniques have been used for getting rid of these ions from wastewater, such as membrane separation, chemical reduction, chemical precipitation, ion exchange, adsorption, and biological treatment. , Growing attention has recently given to chelating resins because they are simple, work well, durable, separated easily, and possess higher metal ion sorption capacities and selectivity. − The removal of metal ions can be achieved by using chelating resins containing functional groups such as amino, amidoxime, carbamate, and iminoacetate which have chelating ability toward divalent metal ions. − Chelating resins with an iminodiacetate functional group such as Amberlite IRC 718, Wafatit MC 50, Lewatit TP 207, Chelex 100, Diaion CR-10, and Purolite S930 were commercially used because of their lower manufacturing costs, higher capacity, and excellent selectivity. − Chelating resins with iminodiacetate functional groups were prepared to remove hazardous metal ions from wastewater containing metal ions such as copper, cadmium, nickel, lead, manganese, mercury, and zinc due to their high selectivity. − In our earlier works, a chelating resin with iminodiacetate groups was synthesized through subsequent treatment of cross-linked polyacrylamide by ethylenediamine and sodium chloroacetate . The prepared resin was studied for efficient adsorption of some metal ions such as lead, cadmium, manganese, and zinc .…”

A new type of magnetic chelating resin (MIDA) beads bearing iminodiacetate groups derived from acrylamide−N,N′-methylenebis(acrylamide) copolymer was synthesized in the presence of Fe 3 O 4 nanoparticles and tested for the removal of Cu(II), Pb(II), Zn(II), and Cd(II) from aqueous solution. The prepared Fe 3 O 4 nanoparticles were characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM)-energy dispersive X-ray, transmission elelctron microscopy, and X-ray diffraction (XRD). The obtained MIDA was characterized by FTIR, SEM, Brunauer−Emmett−Teller analysis, XRD, thermal analysis, and water regain (W%). Different factors affecting the adsorption process such as pH of solution, initial concentration of the metal ions, shaking time, and temperature of solution, were investigated by batch technique. The maximum adsorption capacities were 4.1, 3.6, 2.4, and 2.2 mmol•g −1 for Cu(II), Pb(II), Zn(II), and Cd(II), respectively. Langmuir isotherm and pseudo-second-order equation could adequately describe the adsorption process of all metal ions. Thermodynamic parameters revealed that the adsorption process is endothermic, spontaneous in nature, and entropy driven. Additionally, the removal of Cu(II) was tested using the fixed-bed column technique. The effect of significant column parameters such as bed height, flow rate, and Cu(II) concentration on the performance of the column were examined. The breakthrough curves obtained were analyzed by Thomas and Yoon−Nelson kinetic models. The regeneration of the exhausted column bed was conducted with 0.1 M HNO 3 solution, and MIDA was found to maintain its high adsorption capacity up to six cycles.
