“…Pyrocatechol violet (PCV, with the chemical structure shown in Scheme ), a dye in the triphenylmethane series, has been used for the determination of Al 3+ 32, 33 and other metal ions 34. The monomer dyes possess very good electrocatalytic activity toward the redox of small molecular compounds such as ascorbic acid and dopamine,35 hydrazine,36 and NADH,37 displaying excellent electron transform efficiency as an electron transfer mediator.…”

In this work, a new hydrogen peroxide (H 2 O 2 ) sensor was reported based on electropolymerizing pyrocatechol violet (PCV) on a glassy carbon electrode modified with multiwalled carbon nanotubes (MWCNTs). The modified electrode was characterized by cyclic voltammetry (CV) and scanning electron micrography. The result of electrochemical experiments showed a favorable catalytic activity toward the reduction of H 2 O 2 at À0.4 V with a linear response range from 2.0 lM to 2.4 mM and a detection limit of 0.7 lM (at a S/N ¼ 3). The well catalytic activity of proposed sensor could be attributed to the poly-PCV/MWCNTs composite film on the electrocatalytic reduction of H 2 O 2 . In addition, the sensor also exhibited a high sensitivity, good stability, and reproducibility.

“…Due to the adsorption of the aluminium complex on the working electrode surface, the reduction potential displaces to more positive values [4,5]. Most of the works based on this procedure use a hanging drop mercury electrode (HDME) as working electrode [23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38][39]. Spite of the high sensitivity of this electrode in the determination of metal species, it has to be considered the mercury toxicity.…”

“…However, the sensitivities of these methods remain poor. The voltammetric response of an electroactive ligand that forms a complex with Al(III) were changed in the presence of Al(III), which provides an indirect electrochemical strategy for the determination of Al(III) [ 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 ]. There also are a few biosensors developed for Al(III) [ 42 , 43 , 44 ].…”

Direct detecting of trace amount Al(III) in aqueous solution by stripping voltammetry is often frustrated by its irreversible reduction, resided at −1.75 V (vs. Ag/AgCl reference), which is in a proximal potential of proton reduction. Here, we described an electroanalytical approach, combined with liquid phase microextraction (LPME) using ionic liquid (IL), to quantitatively assess trace amount aluminum in environmental samples. The Al(III) was caged by 8-hydroxyquinoline, forming a superb hydrophobic metal–chelate, which sequentially transfers and concentrates in the bottom layer of IL-phase during LPME. The preconcentrated Al(III) was further analyzed by a square-wave anodic stripping voltammetry (SW-ASV). The resulting Al-deposited electrodes were characterized by scanning electron microscopy and powder X-ray diffraction, showing the intriguing amorphous nanostructures. The method developed provides a linear calibration ranging from 0.1 to 1.2 ng L−1 with a correlation coefficient of 0.9978. The LOD attains as low as 1 pmol L−1, which reaches the lowest report for Al(III) detection using electroanalytical techniques. The applicable methodology was implemented for monitoring Al(III) in commercial distilled water.
