“…In the case of In(III), analytical methods for trace determination include ETAAS [ 30 , 45 , 49 , 50 , 51 , 52 , 53 , 54 ], FAAS [ 27 , 55 , 56 ], ICP-OES [ 57 , 58 , 59 , 60 ] and ICP-MS [ 61 , 62 , 63 ]. To a lesser extent, because they do not achieve sufficient sensitivity, Vis-UV molecular absorption spectrometry [ 46 , 47 , 64 , 65 , 66 , 67 , 68 ] and electrochemical methods are used [ 40 , 41 ].…”

Using a Simple Magnetic Adsorbent for the Preconcentration and Determination of Ga(III) and In(III) by Electrothermal Atomic Absorption Spectrometry

et al. 2023

A solid-phase dispersive microextraction procedure has been developed using ferrite (Fe3O4), an inexpensive magnetic material, as an adsorbent for the separation and subsequent determination of Ga(III) and In(III). The ions were removed from an aqueous solution by adsorption on Fe3O4, which was next easily collected from the medium by the action of a magnet. The analytes were then desorbed using 50 µL of 2 M NaOH or 50 µL of a 4:1 mixture of 0.1 M EDTA and 2 M HNO3 for the determination of Ga(III) or In(III), respectively. The level of the elements in the desorption phase was measured by electrothermal atomic absorption spectrometry (ETAAS) by injecting 10 µL of this phase into the atomizer. The enrichment factor was 163, and detection limits of 0.02 and 0.01 µg L−1 were achieved for Ga(III) and In(III), respectively. The reliability of the procedure has been verified by means of standard reference materials and by means of standard additions. Results are given for waters, soils and samples obtained from various electronic devices. It is of note that the procedure could be the basis for a useful way of recovering these valuable elements from different matrices for reuse.

“…Solid-phase extraction, in its different variants, has received more attention. Silica gel [ 49 ], chelating resins with suitable ligands [ 45 , 46 , 52 , 54 , 59 ], coprecipitation with chitosan [ 53 ] and sodium dodecyl sulphate modified activated carbon [ 50 ] have been proposed.…”

“…Currently, there is growing interest in the preparation of such materials based on different forms of silica [31][32][33][34]. Covalent immobilization of ionic liquids is often carried out on the surface of commercially available pre-functionalized silica gels to obtain new stationary chromatographic phases for the separation of amino acid mixtures and different organic and inorganic anions [35][36][37][38].…”

Imidazolium-Modified Silica Gel for Highly Selective Preconcentration of Ag(I) from the Nitric Acid Medium

2022

View full text Add to dashboard Cite

The ion-exchange behavior of an organomineral material with an imidazolium (1-methyl-3-(prop-2-yn-1-yl)-1H-imidazol-3-ium bromide)-modified silica gel was studied for the extraction of Ag(I) from nitric acid media. The extraction from multicomponent systems containing Fe(III), Co(II), Ni(II), Cu(II), Pb(II), and Mn(II) in 100- and 1000-fold molar excesses with respect to Ag(I) was shown to occur with high selectivity. Based on the data of X-ray diffraction and X-ray fluorescence spectroscopy for samples of modified silica gel, a mixed ion exchange–adsorption mechanism for the extraction of Ag(I) was proposed. The effect of the phase contact time and the concentration of nitric acid on the distribution coefficient of Ag(I) was studied. The selectivity factors of the extraction of Ag(I) from multicomponent systems containing foreign cations in 100- and 1000-fold molar excesses under steady-state and dynamic concentration conditions were calculated.
