“…The incubated electrodes were used for the determination of Cu ions using DPV technique. The optimum pH value was determined to be 5.00 from this study and this result is supported by some studies [38][39][40][41][42]. At higher pH values, Cu ions cannot be detected due to the precipitation formation as hydroxide.…”

a b s t r a c tIn this research, (Z)-2-(2-(hydroxyimino)-2-(3-methyl-3-phenylcyclobutyl)ethyl)-3a,7a-dihydro-1H-isoindole-1,3(2H)-dione, HMPD molecule has been grafted to the glassy carbon (GC) electrode surface. The HMPD-modified GC electrode has been originally developed and it used for the quantitative determination of Cu(II) in flour and water samples. The modification steps have been performed using cyclic voltammetry (CV). CV, electrochemical impedance spectroscopy and scanning electron microscopy have been employed for the characterization processes. Cu(II) standard solutions changing from 1.0 × 10 -9 to 1.0 × 10 -3 M have been prepared and the corresponding peak currents have been measured. From the obtained data calibration equation has been calculated I p = -1.555C cu + 15.86 which is having a 0.9974 correlation coefficient. 10.0 mL of flour and water samples have been mixed with 10.0 mL Britton-Robinson (BR) buffer solution (pH = 5.00) and HMPD/GC sensor electrode has been kept in these mixed solutions for 90 min. Differential pulse voltammetric (DPV) technique has been applied for the measurement of the peak currents. After the application of the developed sensor electrode for Cu(II) detection in flour and water samples, Cu(II) ion concentrations have been calculated from the obtained peak current values, 1.97 and 2.46 µA. The Cu(II) ion concentrations have been calculated as 1.17 × 10 -9 and 2.41 × 10 -9 M, respectively.

“…6,7 For example, Deshmukh and co-workers reported that the determination of the heavy metal ions Cu 2+ , Pb 2+ , and Hg 2+ on the stainless steel electrode (SS) modied with ethylenediaminetetraacetic acid (EDTA) chelating ligand modied polyaniline 8 and singe walled carbon nanotubes (SWCNTs) based nanocomposite (EDTA-PANI/SWNCTs), and the limit of detection the modied electrode toward Cu 2+ , Pb 2+ , and Hg 2+ was determined as 0.08 mM, 1.65 mM and 0.68 mM, respectively. 9 EDTA chelating ligand graed onto PANI and SWCNTs improved the binding ability of heavy metal ions and the conductivity of the materials, respectively. At the same time, the research results also showed that the electron-conducting ability and the binding ability toward heavy metal ions of the composite materials are the key factors affecting the sensitivity of the modied electrode.…”

“…Electrochemical detection of heavy metal ion concentration is a versatile tool. Anodic stripping voltammetry (ASV) is the commonly used technique (Bansod et al, 2017;Deshmukh et al, 2018a). However, ASV has weaknesses such as instability, low sensitivity, and limits to detection (Zhao et al, 2014;Patil et al, 2018).…”

Electrochemical recognition of Hg (II) ions utilizing EDTA modified polyaniline (PANI)/Graphene Oxide (GO) composite is reported in the present communication. Graphene Oxide (GO) synthesis was carried out by a modified Hummer's method. Electrochemical characterizations, namely cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), were performed before and after modification of the composite. The topographies of the PANI/GO composite and EDTA_PANI/GO electrodes were studied using AFM. Roughness parameter values were compared for confirmation of surface modification. Fourier transform infrared spectroscopy (FTIR) was utilized for the compositional analysis of PANI/GO and EDTA_PANI/GO electrodes. The EDTA_PANI/GO composite exhibits sensitivity toward Hg (II) ions when probed using the differential pulse stripping voltammetry (DPSV) technique with a lower detection limit of 2 ppb. EDTA modified SS_PANI/GO composite (PANI/GO composite deposited on a stainless-steel substrate) showed superior sensitivity in the detection of Hg (II) ions. The sensitivity was observed to extend to 1 ppb, which is smaller than the maximum contaminant level (MCL) endorsed by the Environment Protection Agency (EPA, United States).
