“…This ligand was appended onto a crosslinked polystyrene resin XAD-4 and adsorption properties of La(III), Nd(III) and Sm(III) towards this resin were studied [11]. El-Dessouky and Borai [12] studied the extraction chromatography of thorium ion by solid phase impregnated resins containing bi-functional organic extractant. They found that the impregnated resin containing CYANEX-301 and 15C5 can be utilized for selective separation and preconcentration of thorim ion from nitrate medium in the presence of several interfering ions.…”

“…EI‐Dessouky and Borai 48 impregnated XAD‐7 with a mixture containing Cyanex 301 (bis(2,4,4‐trimethylpentyl)dithiophosphinic acid) and one neutral extractant from the following: dibenzo‐18‐crown‐6 (DB18C6), 18‐crown‐6 (18C6), and 15‐crown‐5 (15C5) at 1:1 molar ratio. It was verified that a mixture of Cyanex 301 and 15C5 was the preferable choice with a strong synergic effect for selective separation and preconcentration of Th(IV) from nitrate medium.…”

The recovery and separation of metals from aqueous solutions is one of the research hotspots in hydrometallurgy, environment protection, analytical chemistry, etc. Much attention has been paid to solvent‐impregnated resins (SIRs) since these were firstly proposed for the extraction of metals. SIRs are characterized by high efficiency and selectivity, convenient preparation, and easy operation because they combine the unique advantages of solvent extraction and ion exchange. The preparation and features of SIRs are summarized and their applications in the extraction of various metals from solutions are reviewed. In addition, the equilibrium, thermodynamics, and sorption kinetics of the metals onto SIRs are elucidated in detail.

“…During the impregnation process, Cyanex 272 was diluted in acetone. Hexane [ 17 ] and chloroform [ 18 ] were also used as extractant solvents. One of the objectives of this paper was to develop a method of impregnation without the use of potentially toxic organic solvents, e.g., chloroform.…”

A New Impregnated Adsorbent for Noble Metal Ion Sorption

Noble metals (NM) such as gold, platinum, palladium, and rhodium are widely applied in the electronics and automotive industries. Thus, the search for cheap and selective sorbents for noble metals is economically justified. Nitrolite does not sorb noble metal ions. A new impregnated sorbent was prepared. The natural sorbent Nitrolite was impregnated with Aliquat 336 using a new warm impregnation method. After the impregnation process, Nitrolite adsorbed platinum(IV), palladium(II), and gold(III) ions from the chloride solutions. The values of the sorption capacity for palladium(II) and platinum(IV) ions were 47.63 mg/g and 51.39 mg/g, respectively, from the 0.1 M HCl model solution. The sorption capacity for gold(III) ions was estimated to be 73.43 mg/g from the 0.1 M HCl model solution. An exhausted catalytic converter was leached, and platinum(IV), palladium(II), and rhodium(III) were transferred to the chloride solution. The impregnated sorbent Nitrolite–Aliquat 336 was used in the investigations of the platinum(IV), palladium(II), and rhodium(III) ions’ sorption from a real solution. The impregnated sorbent Nitrolite–Aliquat 336 proved to be suitable for the recovery of platinum(IV) and palladium(II) ions, whereas rhodium ions were not sorbed from the leached solutions. Notably, 1 M thiourea in the 1 M HCl solution desorbed platinum(IV), palladium(II), and gold(III) above 94%.
