“…In the literature, the determination of aluminium(III) in aqueous solution by voltammetry was achieved via metal-complexation in the presence of complexing agents, such as 1,2-dihydroxyanthraquinone-3sulfonic acid (DASA) [14], alizarin S [15], alizarin violet [16], pyrogallol red [17], 8-hydroxyquinoline [18], cupferron [19], and ionophore JS-1 [20]; using thin mercury film electrodes (TMFE), renewable silver amalgam film electrodes (Hg(Ag)Fe), multi-walled carbon nanotube modified carbon paste electrodes (MWCNT/CPE), mercury electrodes, hanging mercury dropping electrodes (HMDE), HMDEs, and screen-printed carbon electrodes, respectively. Although these chelating agents have shown the capability to form a metal-complex with aluminium ions (Al 3+ ), it is desirable to use alternative materials with a stronger and more selective binding with Al 3+ .…”

The contamination of drinking water and food products by aluminium represents a serious health issue, as it is associated with chronic neurodegenerative diseases. Herein we report an analytical electrochemical method for the determination of aluminium(III) at glassy carbon electrodes, modified with commercially available tannic acid-capped gold nanoparticles. The combination of gold nanoparticles and tannic acid as capping/chelating agent results in an accurate and sensitive detection of aluminium(III) in aqueous solutions by square wave voltammetry (SWV). Employing the presented methodology, clear measurable signals are seen even at the low limit of 10.0 pM, markedly and usefully lower than the permissible level of 7.4 µM for drinking water as defined by the WHO and which compares favourably with alternative detection methods.

“…With its high sensitivity and rapid analysis time, electrochemical determination of the Al(III) level could be ideal for routine monitoring. A range of electrochemical sensors has been reported in the literature, based on enzyme inhibition , and different complexing agents of metal ions , such as (poly)phenols ,− or zeolites. , These sensors, however, suffer from different drawbacks: low sensitivity or precision, use of mercury electrodes, and sensitivity to interfering species, and none of them can be selectively deposited on microarray electrodes. ,,,,− ,− Most of them were designed for (i) Al(III) sensing in acidic conditions ,,,− and/or (ii) in physiological conditions but in the absence of serum proteins. ,, …”

Electrochemically triggered self-assembly can be effectively utilized to produce electroactive materials of tailored properties for various applications, such as sensor development. Here, we present a thin sensor film based on tannic acid (TA) and silver nanoparticles (AgNPs), ionically imprinted via electrodeposition and tailor-designed for electrochemical tracing of aluminum ions, Al(III). In the first stage, the conditions for the Al(III)-printing of TA films onto indium-tin-oxide (ITO) electrode via electrodeposition are established and optimized. To form an AgNPs-containing film, AgNPs are presynthesized via a direct reduction of Ag(I) by TA resulting in TA-stabilized AgNPs (TA@AgNPs) of 1-4 nm in size, as observed by dynamic light scattering. Next, Al(III) ions are added to complex the TA molecules adsorbed on the surface of AgNPs. The resulting Al(III)/TA@AgNPs mixture is then electrodeposited onto ITO surface by applying an anodic potential to form a film. As a result a mesh-structured layer composed of AgNPs with TA on their surface and electrochemically cross-linked via TA-TA covalent bonds at the Al(III)-free coordination sites is formed. The introduction of Al(III) ions bonded via coordination bonds with TA and their consecutive removal using sodium fluoride formed vacancies ready to bind Al(III) ions from the analyzed solution allowing their electrochemical sensing, as monitored by cyclic voltammetry, quartz crystal microbalance (QCM) and X-ray photoelectron spectroscopy. The film was employed for sensing of neurotoxic Al(III) in human serum. A linear correlation between the current value at 0.9 V and the concentration of Al(III) was obtained in the range between 0.10 and 0.298 µM. dried using a filter paper. The grids were observed at 200 kV with a Technai G2 (FEI) microscope. Images were acquired with an Eagle 2k (FEI) ssCCD camera.

“…As hazards of aluminium in environment and humans, determination and separation aluminum in human body and waters is very necessary. Many analytical techniques was used for determination of aluminum in different matrix such as flame atomic absorption spectrometry (F-AAS) [9], stripping Voltammetry (SV) [10], inductively coupled plasma-atomic emission spectrometry (ICP-AES) [11], High performance liquid chromatography/ inductively coupled plasma mass spectrometry (HPLC/ICPMS) [12,13], electrothermal atomic absorption spectrometry (ETAAS) [14] and inductively coupled plasma mass spectrometry (ICP-MS) [15]. Also, sample preparation was needed for separating of contaminations from water and biological samples.…”

A new method for aluminum extraction from drinking water and human serum samples was used by djenkolic acid (DJKA) immobilized on multi-walled carbon nanotubes (MWCNTs-DJKA). In the optimized study, LOD, LOQ, the linear range, the working range, and the enrichment factor were obtained 0.1 µg L−1, 0.3 µg L−1, 0.3-12.8 µg L−1, 0.3-30.7 µg L−1 and 9.92, respectively (RSD< 5%). The adsorption capacity of the MWCNTs-DJKA and MWCNTs sorbent was achieved 122.6 mg g-1 and 33.7 mg g-1 in the batch system for 20 min, respectively. The mean aluminum in drinking water and serum samples were obtained 48.56 ± 2.92 and 11.64 ± 0.73 which was lower than the reference value in drinking water and human biological samples. The method was validated by spiking samples and standard reference materials (SRM) in water and human biological samples.
