“…Aluminium extraction was found to be low over all pHs tested and similar results are reflected in other studies [45]. Thorium uptake increases with decreasing acidity, yet does not reach 100 % extraction at any pH examined and also decreases with increasing sulfate ) [50][51][52][53]. )…”

“…However, in a previous study, when the resin was loaded from a mixed solution where the molar concentration of metals in solution was greater than the capacity of the resin available, ferric iron uptake was suppressed to less than 20 % extraction at acidities of 0.1 and 0.01 M [H + ] and decreased even further with decreasing acidity, compared to the 32 and 84 % extraction for this study respectively [45].…”

“…The weak base chelating resin, Dowex M4195, with bis-(picolyl)amine functionality, has demonstrated unique separation capabilities for first row transition metals. It has been investigated for the extraction of Cu(II) [10][11][12][13][16][17][18], Ni(II) [13][14][15][16][17][18][19], Co(II) [14-16, 18, 19], Cr(III)/(VI) [21,22], Zn (II) [13,15], Cd (II) [13,15], Pd(II) [14,15,23], Au(III) [15], Pb(II) [14,19] Fe(III) [14,19], Mn(II) [14,19], and Pt(IV) [15]. To the best of our knowledge, the application of Dowex M4195 to separate uranium from acid-based streams has not been carried out.…”

Using present technologies, the increased salinity from these water sources results in decreased uranium extraction and increased extraction of impurities. There is incentive to overcome these challenges, either through new technologies, or repurposing existing technologies. The ion exchange behaviour of U from sulfate media on the weakly basic chelating resin Dowex M4195 (bis-picolylamine functionality) and the effect of competing chloride and impurity metal ions (Th, Fe, Al, Cu, Ni) has been studied. Experiments to determine acid, and sulfate media behaviour, and extraction thermodynamics including the effect of increasing chloride concentration upon extraction behaviour were carried out.

“…Cobalt and nickel can be easily separated from manganese and magnesium at pH 4 and 5. Mendes 44) found Dowex M4195R (whose functional group is bis-picolylamine) has good performance both for nickel and cobalt at low pH such as pH = 1.0. While at pH = 4, IRC 748 is selective for copper, nickel and cobalt.…”

Recovery of pure cobalt and nickel from diverse resources is important due to the increased demand for these metals. In order to get cobalt and nickel with high purity, separation of them from other metal ions is necessary. In this review, several methods to obtain pure cobalt or nickel solution, such as solvent extraction, ion exchange, precipitation were introduced and compared. For solvent extraction, the advantage and disadvantage of the separation process together with detailed process conditions were investigated.

“…Por otra parte, esta resina se ha utilizado con soluciones provenientes de la industria de galvanoplastia, para el tratamiento de los efluentes de este proceso (Swing et al 2003). Además, con esta misma resina se han obtenido resultados favorables en la remoción de Co y Ni, en un estudio realizado con soluciones sintéticas y a partir de un licor de lixiviación (Mendes et al 2004). …”

Palabras clave: metales pesados, quelante, capacidad de adsorción RESUMEN El objetivo de este trabajo fue evaluar la capacidad de la resina quelante Dowex M-4195 para la remoción de hierro y manganeso, a partir de soluciones de dos fuentes: una proveniente de la infiltración de una presa de jales en desuso (J1) y otra de agua residual del proceso de recuperación de cobre (M1). Se aplicó el modelo de Langmuir para determinar la capacidad de adsorción de la resina. El análisis de los resultados muestra una capacidad de adsorción de 7.5 mg Fe/g de resina y 4.0 mg Mn/g, con remoción de 70 y 25 %, respectivamente para la muestra J1 en un tiempo de contacto de 12 h. Para la muestra M1 fue de 12.5 mg Fe/g y de 2.96 mg Mn/g, con remoción del 58 y 20% para cada metal, en un tiempo de contacto de 5 h. Los resultados del análisis de espectroscopía de infrarrojo de transformada de Fourier (FTIR) muestran las modificaciones en los enlaces del grupo funcional de la resina debido a la adsorción de los metales. Estos resultados indican que el uso de la resina quelante Dowex M-4195 puede ser una alternativa a los tratamientos convencionales para la recuperación o remoción de metales pesados de soluciones acuosas.Key words: heavy metals, chelating, adsorption capacity ABSTRACTThe objective of this study was to evaluate the ability of removing iron and manganese in the chelating resin Dowex M-4195, from solutions of the infiltration from a tailing dam (J1) and a wastewater in copper recovery process (M1). The Langmuir model was used to determine the adsorption capacity of the resin. The results show an adsorption capacity of the resin of 7.5 mg Fe/g and 4.0 mg Mn/g with a removal of 70 and 25 %, respectively for sample J1, with a contact time of 12 h. For sample M1 it was obtained 12.5 mg Fe/g and 2.96 mg Mn/g, with a removal of 58 and 20 % for each metal with a contact time of 5 h. Results of FTIR analysis show modifications in the functional groups bonded to the resin due to adsorption of metals. These results indicate that the use of resin Dowex M-4195 can be an alternative to conventional treatments for the recovery or removal of heavy metals from aqueous solutions.
