“…This method requires a lower oxidation potential, in which several novel electrodes have been developed, such as the Rh 2 O 3 /Ti electrode [57] and copper nanoparticle electrode [56]. Although there are several electrochemical sensors developed in laboratory tests, more evaluation and validation are still required to be used for in situ monitoring of the COD in natural water (e.g., lakes and rivers) and the effluent of wastewater treatment plants [38,39]. Currently, there are no available BOD and COD sensors for field uses.…”

Water quality control and management in water resources are important for providing clean and safe water to the public. Due to their large area, collection, analysis, and management of a large amount of water quality data are essential. Water quality data are collected mainly by manual field sampling, and recently real-time sensor monitoring has been increasingly applied for efficient data collection. However, real-time sensor monitoring still relies on only a few parameters, such as water level, velocity, temperature, conductivity, dissolved oxygen (DO), and pH. Although advanced sensing technologies, such as hyperspectral images (HSI), have been used for the areal monitoring of algal bloom, other water quality sensors for organic compounds, phosphorus (P), and nitrogen (N) still need to be further developed and improved for field applications. The utilization of information and communications technology (ICT) with sensor technology shows great potential for the monitoring, transmission, and management of field water-quality data and thus for developing effective water quality management. This paper presents a review of the recent advances in ICT and field applicable sensor technology for monitoring water quality, mainly focusing on water resources, such as rivers and lakes, and discusses the challenges and future directions.

“…Amperometric detection showed linear range 2-595 mg/L and limit of detection (LOD) 2.6 mg/L. (Hassan et al, 2018) Cu is also deliberately used in OLEDs (organic lightemitting devices). (Bizzarri et al, 2018) The technology of ultrathin metal layers deposition on flexible substrates is believed to be an alternative for ITO (indium tin oxide) anodes, as ITO is brittle and indium is considered to be poisonous.…”

Copper is an important metal in analytical and industrial fields as it has excellent thermal and electrical properties. In many disciplines, like electronics, optics, and others, copper nanoforms pay more attention than other noble metals nanoparticles. Attractive are its natural abundance, low costs and high activity toward many analytes with simultaneous physical stability. Extensive use has brought new types of sensors and practical implementations. The objective of this paper is to present crucial developments of copper material in the sensing field. Practical applications in the environmental section, like chemical oxygen demand measurement or carbon dioxide reduction reaction for atmospheric CO2 reduction; technological sensors like organic light-emitting devices, electronic tongue for alcohol type determination, human skin touch and move sensor; and medical sensors for glucose, alcohol, dopamine or paracetamol detection were presented.

“…Involvement of copper (II) and copper (III) in the oxidations of organic compounds is quite possible since these species (Cu (II) and Cu (III)) are present in this potential range [41]. A similar mechanism was proposed for the enhancement of the catalytic activity of nanocopper and nano-nickel based COD sensors [50,21].…”

Copper nanoparticles (nano‐Cu) were electrodeposited on the surface of glassy carbon electrode (GCE) potentiostatically at −0.6 V vs. Ag/AgCl for 60 s. The developed nano‐copper modified glassy carbon electrode (nano‐Cu/GCE) was optimized and utilized for electrochemical assay of chemical oxygen demand (COD) using glycine as a standard. The surface morphology and chemical composition of nano‐Cu/GCE were investigated using scanning electron microscope (SEM) and energy dispersive X‐ray spectrometer (EDX), respectively. The electrochemical behavior was investigated using linear sweep voltammetry (LSV) which is characterized by a remarkable anodic peak at ∼0.6 V, compared to bare GCE. This indicates that nano‐Cu enhances significantly the electrochemical oxidation of glycine. The effect of different deposition parameters, such as Cu2+ concentration, deposition potential, deposition time, pH, and scan rate on the response of the developed sensor were investigated. The optimized nano‐Cu/GCE based COD sensor exhibited a linear range of 15 to 629.3 ppm, and a lower limit of detection (LOD) of 1.7 ppm (S/N=3). This developed method exhibited high tolerance level to chloride ion (0.35 M chloride ion has minimal influence). The analytical utility of the prepared COD sensor was demonstrated by investigating the COD recovery (99.8±4.3) and the assay of COD in different water samples. The results obtained were verified using the standard dichromate method.
