“…OMC materials by themselves are attractive electrode substrates for electrochemical sensing owing to their attractive properties (large conducting surface area, regular and widely open nanostructure, catalytic edge-plane-like sites, or oxygenated surface functions). Table 1 gathers all applications of unmodified OMC-based electrochemical sensors reported to date [ 23 , 25 , 43 , 44 , 45 , 53 , 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 , 96 , 97 , <...>…”

“…Several drugs and biologically-relevant molecules, as well as some pesticides, have been detected after accumulation at OMC-modified electrodes. The preconcentration mechanism is not always described but it is possibly due to hydrophobic and/or π–π interactions as most of the investigated species possess aromatic moieties in their molecular structure (i.e., phenol [ 57 , 59 , 72 , 79 , 98 ], nitrophenyl or nitroaromatic groups [ 64 , 78 , 85 , 87 , 89 , 90 ], catechol [ 65 , 97 ], or other aromatic groups [ 60 , 96 , 99 ]). Due to the non-specific nature of these interactions, the sensor selectivity is expected to be rather poor (only controlled by the detection potential) and thus limited in real environmental monitoring (except for spiked samples) but useful to the analysis of drug formulations (pharmaceutical tablets) or foodstuffs, for instance.…”

“…These applications were mostly based on OMC film electrodes ( Table 1 ), but also on carbon paste [ 59 , 89 ] and ionic liquid-based carbon paste electrodes [ 57 , 60 , 65 , 92 , 97 ]. In this last case, the ionic liquid serves as a binder but it could also contribute to accumulate the target analyte.…”

The past decade has seen an increasing number of extensive studies devoted to the exploitation of ordered mesoporous carbon (OMC) materials in electrochemistry, notably in the fields of energy and sensing. The present review summarizes the recent achievements made in field of electroanalysis using electrodes modified with such nanomaterials. On the basis of comprehensive tables, the interest in OMC for designing electrochemical sensors is illustrated through the various applications developed to date. They include voltammetric detection after preconcentration, electrocatalysis (intrinsically due to OMC or based on suitable catalysts deposited onto OMC), electrochemical biosensors, as well as electrochemiluminescence and potentiometric sensors.

In this paper, a highly defective mesoporous carbon (DMC) and room temperature ionic liquid 1-butyl-3methylimidazolium hexafluorophosphate (BMIM$PF 6 ) were applied to fabricate a novel carbon paste electrode for the electrochemical sensing of rutin. The electrochemical properties of rutin on the modified electrode (IL/DMC/PE) were carefully investigated by cyclic voltammetry, electrochemical impedance spectroscopy and chronocoulometry. Electrochemical parameters of rutin on the surface of the modified electrode were determined with the electron transfer coefficient (a) as 0.53, the electron transfer number (n) as 2, the heterogeneous electron transfer rate constant (k s ) as 37.1 s À1 , the diffusion coefficient as 1.34 Â 10 À4 cm 2 s À1 and saturated absorption capacity as 10.9 nmol cm À2 . Under the optimal conditions, rutin could be detected in the concentration range from 0.008 mmol L À1 to 4.0 mmol L À1 with the detection limit as 1.17 nmol L À1 (S/N ¼ 3) by square-wave voltammetry. The proposed sensor was further applied successfully for the determination of rutin content in some real samples, including Ruta graveolens extract, pharmaceutical tablets and orange juice.

Sensitive Approach for Voltammetric Determination of Carbendazim Based on the Use of an Anionic Surfactant

et al. 2016

This report describes by the first time the use of a commercial screen‐printed carbon electrode modified with multi‐walled carbon nanotubes for voltammetric determination of the fungicide carbendazim in the presence of an anionic surfactant. The oxidation of the pesticide showed two anodic and two catodic peaks over a quasi‐reversible system. The quantitative studies were performed using square‐wave voltammetry technique at anodic direction, in that an oxidation peak was observed at +0.98 V vs. Ag/AgCl. Buffer, pH and voltammetric parameters were investigated and optimized. The use of the anionic surfactant sodium dodecyl sulphate provided a significative improvement on analytical sensitivity and its influence also was evaluated. The best conditions for analysis were achieved using a medium of 0.04 mol L−1 Britton‐Robinson buffer at pH 4.00 containing 6.04×10−4 mol L−1 of surfactant. A calibration curve with good linearity (R=0.999) was obtained and the limit of detection achieved was 1.40×10−8 mol L−1 (2.7 ppb). Lastly, the developed method was successfully applied for determination of carbendazim in a spiked orange juice sample and a recovery of 101.7 % was obtained. The results were compared with HPLC technique with good agreement. Based on the data presented, the proposed method shows great promise to be applied in routine analysis of carbendazim in food samples and the approach based on the anionic surfactant effect can be an improvement for other applications.
