“…The peak current of carbaryl decreases before and after this pH value. These results could be attributed to the protonation of the molecules in lower pH and the formation of naphthoxide species at higher pHs . The pH 4 was chosen as working pH for next experiments.…”

A new method has been described for carbaryl determination using a simple electrochemical sensor. The unique properties of poly‐pPhenylenediamine and ionic liquid were exploited to fabricate carbon paste electrode modified with composite based on conducting polymer/ionic liquid. Electrode surface characterization was performed by electrochemical methods (cyclic voltammetry and electrochemical impedance spectroscopy) and by scanning electron microscopy. Differential pulse voltammetry was employed for the detection of carbaryl in acetate buffer solution. Different parameters affecting the carbaryl response were optimized such as ionic liquid amounts, cycle number of polymerization and monomer concentration, pH, and accumulation time. Under the optimum experimental conditions, a linear response was obtained between 0.5 and 200 μmol/L, with detection limit of 0.09 μmol/L. The developed sensor offered satisfactory results for carbaryl detection in spring water and fruit samples.

“…To date, different electrode modifiers are developed for determining CBR and CBF. These sensors include glassy carbon electrode (GCE) modified with MWCNTs/cobalt phthalocyanine and graphene oxide‐ionic liquid composite low silica X zeolite modified carbon paste electrode (CPE) and graphene‐modified boron‐doped diamond electrode for detection of CBR in the real samples. Furthermore, Tan et al., designed a novel molecularly imprinted sensor based on GCE decorated by reduced graphene oxide and gold nanoparticles (rGO@Au) to monitoring of CBF in real vegetable samples Wang et al., for the first time, reported a new electrochemical sensor based on CoO nanoparticle‐decorated reduced graphene oxide (rGO) modified GCE for the simultaneous detection of CBF and CBR .…”

A novel, stable and sensitive non‐enzymatic sensor was developed with metal‐organic frameworks (MOFs) that have attracted great attention in electrochemical sensors applications in recent years. The pore structures of MIL (Fe)‐101 and MIL (Fe)‐53 are the families of MOFs that were constructed via a simple solvothermal procedure. The 35MIL‐101(Fe)‐reduced graphene oxide nanocomposite has been used for modification of glassy carbon electrode for the determination of carbofuran (CBF) and carbaryl (CBR). The porosity of the composites increased the voltammetric responses significantly for CBF and CBR in a mixed solution that makes the simultaneous determination of both carbamate pesticides possible. Characterization of MIL (Fe)‐101 and MIL (Fe)‐53 were performed with FT‐IR, XRD, BET and SEM. Finally, the introduced sensor under the optimal conditions showed low detection limits of 1.2 and 0.5 nM within the linear ranges of 5.0–200.0 nM and 1.0–300.0 nM for CBF and CBR, respectively. The non‐enzymatic sensor was successfully used to monitoring of carbamates residue in vegetable and fruit samples.

“…Electrodes composed of carbon paste are still widely used in electrochemical studies because of their wide potential window, high sensitivity, low background current, and low cost [11]. Many biologically active compounds, e.g., pesticides [12,13], pharmaceuticals [14][15][16], and ions [17][18][19], can be determined using CPEs.…”

In this paper, the fabrication, surface characterisation and electrochemical properties of graphite flake (GFPE) and multilayer graphene (MLGPE) paste electrodes are described. The Raman investigations and scanning electron microscopy were used to analyze and compare structure of both carbon materials. The electroanalytical performance of both electrodes was examined and compared on the basis of the square-wave and cyclic voltammetric behavior of acetaminophen and model redox systems. Results of those studies revealed that GFPE has a larger electroactive surface area and better conductive properties, whilst MLGPE demonstrate better analytical characteristic in case of acetaminophen (AC) determination. AC determination was developed using square wave voltammetry (SWV) and square wave stripping voltammetry (SWSV). For both working electrodes, the process of accumulation enabled us to obtain an extended linear range and to lower the detection limit. In pharmaceutical formulations, AC was determined with good recovery.Sensors 2020, 20, 1684 2 of 15 anisotropic thermal conductivity, with high conductivity in the horizontal direction and low thermal conductivity in the vertical direction [20]. Graphite flakes have found application in electrochemistry as, for instance, a promising anode material for lithium ion batteries [21]. GFs have unique features, including excellent strength and high fracture toughness [22]. Furthermore, the layered graphite structure and weak forces between the layers lead to the possibility of easily refreshing the surface of a paste electrode made of graphite flakes. These properties make graphite flake a promising electrode material [23].Recently, graphene is considered the material of the "rising star" and has received attention due to its unique properties. This form of carbon is considered as a prototype of two-dimensional carbon system and all other dimensionalities [5,24,25]. Graphene can be wrapped into fullerenes (0D), rolled into carbon nanotubes (1D), or used to create graphite (3D) [24]. The development of knowledge related to graphene led to the creation of graphene-based materials. Multilayer graphene (MLG) is a 2D nanomaterial composed of stacked monolayers of graphene. Importantly, both MLG and GNP (graphene nanoplatelets) are composed of graphene layers arranged on top of each other. However, they differ in the number of layers and properties. The number of graphene layers in GNP is greater than 10, while that in MLG varies from 11 to 21 [26]. Experiments show that for model redox systems there is no strong correlation between the flake thickness and the electron transfer rate [27]. However, a higher electron transfer was achieved for flakes consisting of less than 20 graphene layers [27]. The properties of MLG are more similar to those of graphene than to those of graphite [26], and thus make MLG a promising material for the fabrication of carbon paste electrodes.Acetaminophen (AC) is very commonly used in many diseases and pain treatment. Because of its antipyretic and analge...
