“…Although mercury electrodes show lower LODs for the quantitative determination of CPF, the use of mercury may cause environmental problems. In addition, the determination studies performed at RGO/GCE appear to have a lower LOD value compared to those carried out by Sreedar et al, 2015, Kumaravel et al, 2015and Fischer et al J., 2016 Repeatability and Selectivity Repeatability and reproducibility of the proposed sensor were confirmed by taking DPAdSV measurements of 6.03x10 -8 M CPF in 0.1M NaOH at various times using modified electrodes. The RSD value of the peak currents showing the repeatability was 0.069 % with the data obtained at different times using the same electrode.…”

“…Therefore, a simpler, faster and, cost-efficient method is required to detect CPF (Huang et al, 2020). Electrochemical methods were employed for simple, fast and cost-efficient determination of CPF (Al-Meqbali et al, 1998;Manisankar et al, 2005;Pelit et al, 2011;Kumaravel et al, 2015;Sreedar et al,2015;Fischer et al J.,2016;Melo et al,2018;Joshi et al, 2020) Being one of the most prominent elements of the periodic table, carbon has a total of five allotropes including fullerene, carbon nanotube, graphene, graphite, and diamond. While diamond and graphite which have been known since ancient times are three-dimensional allotropes, nanotube discovered in the 90s is one-dimensional and fullerene is zero-dimensional.…”

In this study, the voltammetric behavior of chlorpyrifos(CPF) was investigated using reduced graphene oxidemodified glassy carbon electrode(RGO/GCE). FT-IR, XRD and TEM methods were employed in the characterization of graphene oxide and reduced graphene oxide prepared by Hummers' method. Electrochemical characterization of CPF was determined by cyclic voltammetry(CV) and differential pulse voltammetry(DPV). Determination of CPF was performed by differential pulse adsorptive stripping voltammetry (DPAdSV) on RGO/GCE. Two working ranges between 5.19x10 -7 -8.12x10 -6 M and 8.12x10 -6 -2.18x10 -3 M were obtained in the CPF calibration curve created by DPAdSV method on RGO/GCE and the limit of detection was found to be 1.56x10 -7 M. Recovery of CPF from tap water samples on RGO/GCE was 101.0%. In conclusion, a selective and sensitive sensor was developed for the determination of CPF, which can be used in real samples.

Electrochemical reduction of systemic fungicide azoxystrobin, used to protect a wide variety of crops, was investigated using cyclic voltammetry with a mercury meniscus modified silver solid amalgam electrode (m-AgSAE). Mechanism of the electrochemical reduction was proposed and supported with high performance liquid chromatography/mass spectrometry analysis of azoxystrobin solutions electrolyzed on mercury pool electrode. An analytical method for the determination of azoxystrobin by differential pulse voltammetry with m-AgSAE was developed. The wide linear dynamic range (2.0×10 −6 -5.0×10 −5 mol dm −3 ) and low limit of detection (7×10 −7 mol dm −3 ) were obtained. Accuracy and repeatability of the proposed method was evaluated by the analysis of model solutions with recovery from 96.0 to 104.0 % and relative standard deviation of 5 repeated determinations < 3.5 %. Finally, new voltammetric method using m-MCCM_Template_Vers 4

There are many types of insecticides traded in the local and international markets, which vary depending on the type of target insect (e.g., whether crawling or flying). This paper aimed to assess the concentration of trace elements present in the various pesticide formulations (solid, liquid, and gaseous). This study was conducted in two groups: the first group was comprised of zinc, copper, iron, chromium, phosphorus, selenium, and cobalt; the second group included four heavy toxic elements (arsenic, thallium, lead, and mercury). These elements were analyzed by inductively coupled plasma/optical emission spectrometry (ICP-OES).
