“…The similar response of electrochemical current has been reported elsewhere in the detection of the heavy metal ion in aqueous medium. 64,65 At the initial stage of sensing performance of Ag + ions, a small electrode coverage on the surface of PVC-MG-CNT NCs/nafion/GCE electrode is observed due to the adsorption of few Ag + ions. Then, with enhancement of Ag + ion in sensing aqueous medium, the rate of corresponding reaction increased significantly as well as enhanced the surface coverage.…”

Polyvinyl chloride/mixed graphene-carbon nanotube nanocomposites have been fabricated in the form of (PVC/MG-CNTsa-e) via simple dissolution method with the help of ultrasonic assistance. First, mixed G:CNTs ratio (50:50) wt by wt was prepared. Then, different loadings of that mixed G/CNTs ratio (2, 5, 10, 20, and 30 wt %) were added to the PVC polymer matrix. The fabricated PVC/MG-CNTsa-e nanocomposites were characterized by different techniques including: FT-IR, XRD, SEM, TEM and thermal analyses. The perception found in the FT-IR results of PVC nanocomposites confirm the introduction of mixed G/CNTs nanoparticles in the PVC polymer matrix. The mixed G/CNTs were stimulated in highly regular order in the PVC film and its crystallinity was significantly improved. The thermal property of pure PVC polymer matrix was noted to be highly improved by combining the mixed G/CNTs in the form of nanocomposites. CDTmax for all the samples were nearly similar and appeared in the same range of 270–305℃. Here, a potential Ag+ ionic sensor has been fabricated based on the glassy carbon electrode coated by PVC/MG-CNT NCs to make a thin layer as working electrode probe. The slope of the calibration curve plotted as current versus the concentration of Ag+ ion was used to calculate the sensitivity (6.4241 µAµM−1cm−2) by considering the active surface area of the sensor probe. The current observation based on Ag+ ionic concentration is found to be linear over the linear dynamic range, where the detection limit (DL = 14.78 ± 0.74 pM) is measured by considering the signal to noise ratio at 3. Considering the application feature of Ag+ ion sensor, the proposed sensor was demonstrated to have good reproducibility and reliability for the sensor application through the determination of toxins in environmental and healthcare fields at broad scales.

“…Furthermore, it caused an increase in the π-π* interaction between the functional groups of ATNA and Cr 3+ ions, which is responsible for the change in the current response, Scheme 4b. The same phenomena based on the above stipulated proposed mechanism for the detection of toxic chemicals have also been cited in the literature [59,60]. In order to optimize the newly designed ATNA/Nafion/GCE as sensitive as well as a selective and efficient Cr 3+ cationic electro-chemical sensor, a concentration variation plot was drawn at the different concentration range of Cr 3+ analytes (0.1 M to 0.1 nM) in addition to the calibration curve at +1.1 V from for above discussed concentration range of Cr 3+ analytes, Figure 7a,b.…”

A new electrochemical sensor of metal cation in an aqueous solution based on homobifunctional tridentate disulfide Schiff base and named 1,1′-(-((disulfanediylbis(2,1-phenylene))bis(azaneylylidene))bis(methaneylylidene))bis(naphthalene-2-ol) (ATNA) was easily obtained quantitatively from the condensation reaction of 2-hydroxy-1-naphthaldehyde and 2-aminothiophenol, and then fully characterized by spectroscopic techniques for structure elucidation. The molecular structure of ATNA was also confirmed by a single-crystal X-ray diffraction study to reveal a new conformation in which the molecule was stabilized by the O–H…N type intramolecular hydrogen bonding interactions in both moieties. The ATNA was used as a selective electrochemical sensor for the detection of chromium ion (Cr3+). A thin film of ATNA was coated on to the flat surface of glassy carbon electrode (GCE) followed by 5 % ethanolic Nafion in order to make the modified GCE (ATNA/Nafion/GCE) as an efficient and sensitive electrochemical sensor. It was found to be very effective and selective against Cr3+ cations in the company of other intrusive heavy metal cations such as Al3+, Ce3+, Co2+, Cu2+, Ga3+, Hg2+, Mn2+, Pb2+, and Y3+. The detection limit at 3 S/N was found to be 0.013 nM for Cr3+ ions within the linear dynamic range (LDR) (0.1 nM–10.0 mM) of Cr3+ ions with r2 = 0.9579. Moreover; this work instigates a new methodology for developing the sensitive as well as selective electrochemical toxic cationic sensors in the field of environmental and health care.
