“…proposed to use BDD electrode as a sensor for the pesticide parathion and found slight improvement in the performance of BDD compared to hanging mercury electrode. BDD is also able to detect carbamate pesticides like aldicarb, cabaryl, propoxur methomyl, and carbofuran as reported by Selva and Da Paixão . Triclopyr, a pyridine herbicide is also detected successfully by BDD electrode using voltammetric method .…”

The chemical stability and electrocatalytic properties of boron‐doped diamond (BDD) electrodes give rise to various applications. While wastewater treatment is the most widely studied field, the use of BDD for soil remediation and environmental sensing is currently investigated more and more. With regards to soil remediation, promising results have been reported for the treatment of soil washing solutions. Anodic oxidation using BDD at high current density allows high mineralization rates of biorefractory soil pollutants and extracting agents to be reached. At low current density, selective degradation of target pollutants has been achieved, thus allowing the reuse of extracting agents for further soil washing steps. BDD‐based electrochemical sensors have been studied for chemical oxygen demand determination, pesticide/pharmaceutical detection as well as other applications such as pH, O2 and analysis of various organic and inorganic compounds. Low detection limits, wide linear ranges and low standard deviations have been achieved. The main reasons behind the superiority of BDD sensors are the chemical stability, wide applicability and resistance of BDD towards biofouling. The beauty of BDD sensing is that it can work for a variety of organic and inorganic compounds under many physicochemical parameters.

“…Therefore, the development of simple, highly selective and accurate analytical methodologies for pesticide determination in environmental and food samples has become a key issue. In this context, electroanalytical approaches have been successfully applied for carbamate pesticide detection in several matrices due to the remarkable versatility of these methods [12][13][14]. Selection of the most appropriate sensing material is a crucial step.…”

This study describes the development of a simple and accurate methodology for carbamate pesticide formetanate (FMT) analysis in fruits based on the use of a boron-diamond doped electrode (BDDE) cathodically pretreated and on the forward component of the current of square-wave voltammetry (SWV). FMT exhibits a well-defined irreversible oxidation process, which reaction mechanism is diffusion-controlled, involves the participation of one electron and is influenced by the electrolyte pH. However, protonation does not participate in the ratedetermining step in the redox process. The optimum experimental and voltammetric conditions were pH 7.0 (0.04 mol L −1 Britton-Robinson buffer), pulse potential frequency of 20 s −1 , amplitude of the pulse of 25 mV, and height of the potential step of 3 mV. Under the optimum conditions, calibration curve was linear from 4.98 × 10 −7 to 1.70 × 10 −5 mol L −1 FMT with a limit of detection of 3.7 × 10 −7 mol L −1. FMT sensing was performed in different fruits (mango and grape). Recoveries ranged from 95.2 ± 2.8 to 104.0 ± 3.5% for mango and 96.5 ± 2.5 to 105.2 ± 3.5% for grape proving the accuracy and precision of the electroanalytical methodology. The attained data validated the applicability of the developed approach for FMT quantification in fruits.
