“…The analytical determination of aluminium(III) has conventionally been performed using atomic absorption spectrometry (AAS) [7], inductively coupled plasma atomic emission spectrometry (ICP-AES) [8], inductively coupled plasma-mass spectrometry (ICP-MS) [9], neutron activation analysis (NAA) [10], electrothermal atomic absorption spectrometry (ETAAS) [11], UV-vis diffuse reflectance spectroscopy (UV-vis DRS) [12] and spectrophotometry [13]. Although these methods offer reasonable sensitivity and reliability, drawbacks, such as extensive sample preparation, required expertise in handling, expensive instrumentation, and the limitation to ex situ analysis, cannot be avoided.…”

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.

“…The low LOD obtained (see Table 1 ) revealed that the generated Al-MIL-53-N=SA-Br sensor had a better identification of the target ions than reagents/sensors produced using other methods. 25 − 42 Table 2 shows a comparison of our Al-MIL-53-N=SA-Br sensor’s results with several previously described techniques for determining Hg 2+ , Co 2+ , and Al 3+ ions using other reagents/sensors. Our suggested Al-MIL-53-N=SA-Br sensor has a lower LOD than the other reagents/sensors, according to the data.…”

A modified metal–organic framework (MOF) named Al-MIL-53-N=SA-Br was synthesized via a Schiff-base reaction between the MOFs (Al-MIL-53-NH 2 ) and 5-bromo salicylaldehyde. The robust functionalized Al-MIL-53-N=SA-Br was used as a novel spectrophotometric sensor for detecting Hg 2+ , Co 2+ , and Al 3+ ions. In a wide range of concentrations, the absorption spectral intensity of Al-MIL-53-N=SA-Br increased linearly upon increasing the concentration of Hg 2+ , Co 2+ , and Al 3+ ions. The limit of detection (LOD) of the proposed Al-MIL-53-N=SA-Br sensor reached 1.52 ppm of Hg 2+ ion (7.56 × 10 –9 M). Therefore, this study introduces a novel ratiometric Hg 2+ , Co 2+ , and Al 3+ ions chemosensor. Simple treatment using thiourea or ethylenediaminetetraacetic acid can remove the metal ions from the used sensor and use it many times with a high efficiency. In addition, the Al-MIL-53-N=SA-Br sensor has a high adsorption capacity for these metal ions. The design of the robust Al-MIL-53-N=SA-Br sensor provided high stability, reproducibility, selectivity, high sensitivity, and a facile sensing design. Furthermore, the good absorption spectral stability of Al-MIL-53-N=SA-Br in aqueous media, the broad linear in sensing, and the low LOD of the Hg 2+ , Co 2+ , and Al 3+ ions show its high potential in determining these ions in real water.

“…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.
