“…In artificial seawater, the electrodes responses were quite different (Fig. 5c,5d) and followed the expected trend as Ag is known to interact with chloride and sulphate ions [16,17]. The Ag-SPE presented a clear redox peak for both CV and DPV while the carbon electrodes showed little to no response.…”

“…Besides, silver is known to react with halides to form new components, and this has been thoroughly studied in literature in the form of chloride, iodine, and bromide sensors [14][15][16]. Silver can also react with sulphates to form Ag/AgSO 4 , which has been used as an alternative to the Ag/AgCl reference electrode (RE) [17,18]. Considering that silver readily reacts with components present in water bodies (e.g., NaCl, MgSO 4 ), which could rapidly deteriorate the performance and the lifetime of the sensor, and its high environmental impact, other options for the conductive path material should be explored.…”

Electrochemical probes and sensors have been developed to detect and monitor atmospheric corrosion of metallic materials in the past 40 decades. Depending on the measurement methods, the electrodes and structures of probes and sensors can be different. Various mathematical methods and models have been developed to determine the time-dependent corrosion rate of metal under thin electrolyte film. Polarization techniques such as electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LRP) have the advantage of easy data interpretation but have a tendency to interfere with the corrosion system under investigation. Nonpolarized techniques such as electrochemical noise (EN) do not disturb the corrosion system but data interpretation can be problematic. To achieve long term and reliable corrosion monitoring, optimized electrode design and a multichannel electrochemical instrument are required. New corrosion models and novel data interpretation methods are needed in future work.

“…For these reasons, recently, attention has been paid to electrochemical methods such as voltammetry (VA), with disposable screen-printed electrodes (SPEs) as sensing platforms. Indeed, these approaches have been shown to provide good sensing performance [ 5 , 6 , 7 ], while enabling the possibility of moving the analysis from the lab to in situ [ 8 ]. Furthermore, recently improved performance by modifying SPEs with 2D nanocarbon materials (e.g., carbon nanotubes or graphene nanoplatelets films [ 9 , 10 , 11 ]) was demonstrated.…”

This paper proposes a deep leaning technique for accurate detection and reliable classification of organic pollutants in water. The pollutants are detected by means of cyclic voltammetry characterizations made by using low-cost disposable screen-printed electrodes. The paper demonstrates the possibility of strongly improving the detection of such platforms by modifying them with nanomaterials. The classification is addressed by using a deep learning approach with convolutional neural networks. To this end, the results of the voltammetry analysis are transformed into equivalent RGB images by means of Gramian angular field transformations. The proposed technique is applied to the detection and classification of hydroquinone and benzoquinone, which are particularly challenging since these two pollutants have a similar electroactivity and thus the voltammetry curves exhibit overlapping peaks. The modification of electrodes by carbon nanotubes improves the sensitivity of a factor of about ×25, whereas the convolution neural network after Gramian transformation correctly classifies 100% of the experiments.
