“…Using SPC electrode, (curve 2A ---), potential cathodic peak for IMI was observed at -1.05 V with cathodic peak current of -5.10 µA. This potential value was similar to those reported using BiF [26], graphene oxide [24] and nafion/TiO 2 [27]. Using SWCNT/SPC electrode (curve 2B ---) no signal was observed for the reduction reaction.…”

“…At higher pH values, cathodic peak current decreased considerably. With other modified electrodes, such as Copper (II) phthalocyanine on carbon ceramic electrode [24], graphene oxide on glassy carbon electrode [24], and poly (carbazole)-reduced graphene on glassy-carbon electrode [27] was chosen a pH value close to 7.0 as optimal. For this reason, a pH 7.0 solution is chosen for further studies.…”

The simple modification of a screen printed single walled carbon nanotubes with ionic liquid 1-butyl-3-metilimidazolium tetrafluorborate allowed the development of a fast and selective methodology to determine imidacloprid (IMI). The morphological and conductive characteristics of the modified surface were analyzed with scanning electron microscopy and electrochemical impedance spectroscopy. The modified surface showed great activity towards the reduction of IMI to -1.2 V. The analytical variables were optimized using linear sweep voltammetry at 0.1 V for 60s, obtaining a limit of detection of 0.21 mg L -1 (0.82 µmol L -1 ). Relative standard deviation with six different electrodes was of 2.6 % (n = 5). Finally, the potential interferers were studied and the sensor was applied in the determination of IMI using samples of commercial honey with recovery between 88.0 and 105.0 % for IMI.

<p class="PaperAbstract">The glassy carbon electrode (GCE) was modified by electrochemically reduced graphene oxide (ERGO) and polypyrrole (PPy) prepared by simple cyclic voltammetry (CV) electropolymerization. The PPy/ERGO modified electrode (PPy/ERGO/GCE) was used as a platform of electrochemical sensor to detect imidacloprid (IMI) insecticide. CV and differential pulse voltammetry (DPV) were chosen as the methods to investigate of the electrochemical behavior of IMI on PPy/ERGO/GCE surface. Scanning electron microscopy (SEM) and Raman spectra were utilized to describe the morphology and structure of the modified electrode. Experimental parameters were optimized, such as the number of polymerization cycles, scan rate and the pH value of electrolyte. Under the optimized conditions, when the concentration of IMI was in the range of 1-10 μM and 10-60 μM, the increase of reduction peak current was linear with the concentration of IMI, and the low detection limit was found to be 0.18 μM (S/N = 3). Results showed that PPy/ERGO/GCE demonstrated satisfactory reproducibility and stability, and has great potential in actual sample testing.</p>

“…Electrochemical sensors have emerged in recent years as alternatives for pesticides detection, with benefits related to the low cost, simplicity, high sensitivity and waste reduction, among others 16,17 . The redox properties of IMD and other pesticides allow their detection through electrochemical measurements [18][19][20] .…”
