“…[21][22][23][24][25][26][27][28] Various sophisticated methods are being used for the estimation of aluminum in water and biological samples at concentration levels ranging from the ppm to the sub-ppb levels. [29][30][31][32][33][34][35][36][37][38] It is also interesting that the role of citric acid in forming a complex with aluminum under biological conditions has also been studied. 39,40 The relationship between the concentration of aluminum and poly carboxylic acids, such as tartaric, oxalic, and citric acids, in the rhizosphere and nonrhizosphere of rice soil solution is reported.…”

The coordinating nature of the hydroxy carboxylic acids, such as tartaric and citric acids, has been utilized for the in-situ formation of anions representing the trivalent elements boron and aluminum and two dianions of the hydroxy acid selected under negative electrospray ionization mass spectral conditions. The abundance of these ions could be used for the quantification of boron and aluminum in water at concentrations ranging from 4.0 ppb to 535.0 ppb. For a period of six months, the validity of this method was tested with citric acid as the coordinating agent. Thus, the developed method offers a simple means for the quantification of boron and aluminum in water by negative electrospray ionization mass spectrometry with a single quadrupole mass spectrometer.

“…Until now, various analytical techniques, such as ICP-MS (inductively coupled plasma mass spectrometry) and AAS (atomic absorption spectroscopy), − have been utilized for Al 3+ detection. Nevertheless, their essential problems, including complicated sample preparation, requirement for sophisticated instruments, time allotment, and high cost, often limit their use. , In comparison, luminescence sensing processes have been considered to be among the most compelling approaches and widely employed to detect targeted analytes in low concentrations owing to the distinct advantages of facilitated detection, good sensitivity and selectivity, low-cost operation, real-time monitoring with rapid response, and ease of visualization. ,, Various types of luminescent sensors (turn-on, turn-off, ratiometric) for Al 3+ detection have recently been reported. − ,− However, it is still a challenge to design useful luminescent materials as multifunctional luminescent sensors that exhibit significant luminescence change(s) involving enhancement, quenching, or shift upon stimulation by Al 3+ .…”

A Zn coordination polymer, [Zn(H 2 dhbdc)(Cz-3,6-bpy)] n (1, H 4 dhbdc = 2,5-dihydroxyterephthalic acid, Cz-3,6-bpy = 3,6-bis(pyridin-4-yl)-9Hcarbazole), showing high thermal stability up to 407 °C, has been prepared under hydro(solvo)thermal conditions. Compound 1 has a two-dimensional (2D) undulated layer structure regarded as the topological sql grid, where the tetrahedral Zn(II) centers act as 4-connected nodes connecting by H 2 dhbdc 2− and Cz-3,6-bpy ligands as linkers. Interestingly, the 2D undulated layers expanding in the bc plane are sequentially interwoven with each other in an offset manner along the a-axis, resulting in a condensed polyinterweaving 2D → 3D net. Compound 1 emits weak fluorescence at 522 nm in water suspensions; the intensity can be significantly enhanced by adding Al 3+ ions, with low limit of detection (LOD) of 0.62 μM and high anti-interference ability over numerous competitive metal ions except Fe 3+ ions. Moreover, the detection performance of 1 toward Al 3+ retains high luminescence stability and reusability, being as an excellent candidate for Al 3+ detection over a long period. Spectroscopic evidence from XRPD, EDS, IR, and XPS suggest the occurrence of weak framework−analyte interactions between the H 2 dhbdc 2− ligand units in 1 and the Al 3+ ions, resulting in luminescence turn-on sensing.

A novel amperometric biosensor for the determination of Al(III) based on the inhibition of the enzyme acetylcholinesterase has been developed. The immobilization of the enzyme was performed on screen-printed carbon electrodes modified with gold nanoparticles. The oxidation signal of acetylthiocholine iodide enzyme substrate was affected by the presence of Al(III) ions leading to a decrease in the amperometric current. The developed system has a detection limit of 2.1 ± 0.1 μM for Al(III). The reproducibility of the method is 8.1% (n = 4). Main interferences include Mo(VI), W(VI) and Hg(II) ions. The developed method was successfully applied to the determination of Al(III) in spiked tap water. The analysis of a certified standard reference material was also carried out. Both results agree with the certified values considering the respective associated uncertainties.
