“…A variety of organic chelating agents, such as crown ethers, dithiocarbamates, ␤-diketones, tributyl phosphates, and phosphoric acid derivatives, have been used for SFE of metal ions from various matrices [15][16][17][18]. Meanwhile, acetylacetone (ACAC) is commonly used as a chelating agent in the SFE of metals due to its ease of complex formation, high solubility, and the thermal stability of the metal complexes it forms.…”

“…However, atomic methods have undoubtedly been the most widely used for the determination of Ga(III). In the case of atomic absorption, flame atomization (FAAS) [ 27 , 28 ] and electrothermal [ 29 , 30 , 31 ] techniques (ETAAS) have been proposed, although the narrow linearity range characteristic of this technique has led many authors to use atomic emission spectrometry with optical detection (ICP-OES) [ 32 , 33 , 34 , 35 ] or mass spectrometry (ICP-MS) [ 36 , 37 ] for the purpose. These latter techniques are expensive, mainly due to the high argon consumption.…”

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.

“…Relatively few papers have been written on this subject in the past 15 years. The detection of Ga(III) has been accomplished by a variety of instrumental techniques including AES [5][6][7], ICP [8,9], AAS [10,11] and electrochemical methods [12,13] which always provide satisfying results for their good accuracy. In comparison, some nanoarchitecture based-methodology such as electrochemical, fluorimetry and colorimetry processes have been obtained more attention and displayed large potential for use in various environmentally friendly applications.…”

A new technique for sensing Ga(III) concentration based on polyvinyl alcohol-citrate capped gold nanoparticle-p-aminohippuric acid hybrid (or three-layer core-shell configurations) have been demonstrated. The p-aminohippuric acid capped citrate-gold nanoparticles were comfortably agglomerated in the presence of Ga(III) and the color of the reaction quickly turned from red to violet or blue. Under the detection conditions, a good linear relationship was ideally obtained between the ratio of the absorbance intensity at 620 nm to that at 520 nm (A 620 /A 520 ). The linear response range, the detection and quantification limit was 34.9-418.3 µg/L and 7.6 µg/L and 25 µg/L, respectively. To reflect the accuracy, the developed sensing approach was evaluated 2 against certified reference materials (TMDA 51.3 fortified water and TMDA 28.3 fortified water). This colorimetric strategy was displayed excellent selectivity for Ga(III) over other examined ions. Additionally, the colorimetric method was properly used to detect the concentrations of Ga in tap water and certified reference material samples with recoveries ranging from 95.4 to 102.0%, displaying that the colorimetric procedure could be safely used for a realistic application.
