“…In this century, organic chlorinated compounds such as CPs are the most extensively used chemicals and they exhibit signicant toxicity and carcinogenicity to humans as well as aquatic living organisms due to their non-degradation behavior. 34,35 For decades, 3-CP is an essential raw material for the formulation of pesticides, fungicides, herbicides, antiseptics and wood preservatives. 36,37 Therefore, the environment is continuously polluted by CPs from industrial waste effluents and agricultural activities.…”

A novel multi-metal oxide nanocomposite, Ag 2 O$SrO$CaO, was synthesized by a facile co-precipitation method followed by calcinations. The synthesized nanocomposite was characterized by XRD, FESEM, EDS, TEM, FTIR spectroscopy and photoluminescence (PL) spectroscopy. The composite showed enhanced photocatalytic activity under visible light irradiation and excellent anti-bacterial performance against both Gram-positive and Gram-negative bacteria. Here, the synthesized Ag 2 O$SrO$CaO nanomaterials were deposited on a glassy carbon electrode (GCE) in the form of a thin film to fabricate the desired electrochemical sensor and subjected to I-V analysis of 3-chlorophenol (3-CP) in a phosphate buffer solution (PBS). A calibration curve was plotted from the linear relation of current versus concentration and used to calculate the sensitivity (8.9684 mA mM À1 cm À2 ), linear dynamic range (LDR, 0.1 nM to 0.01 mM) and lower limit of detection (DL, 97.12 AE 4.86 pM). The analytical parameters of the sensor such as response time, reproducibility and long-term stability in the detection of 3-CP were reliable. Finally, it was used to analyze real samples collected from various environmental sources and found to be acceptable.

“…In electrochemical sensors, the Ag/AgCl electrode and saturated calomel electrode (SCE) are the most commonly used reference electrodes. [60][61][62][63][64] This is mainly because they are easy to prepare, and show great stability, working independently from the solution and working electrode during measurement. The introduction of a counter electrode completes the electrical circuit and further improves the potential stability recorded by the reference electrode in the system.…”

“…Enzymes, as well-known biocatalysts, can be modulated onto the surface of basic electrodes to serve as binding recognition receptors in electrochemical sensors. CPs can serve as electron donors for oxidized enzymes such as tyrosinase (TYR), 12,71 polyphenol oxidase, 57,64,118 laccase (Lac), 4,60,119 horseradish peroxidase (HRP), 38,41,62,120 chloroperoxidase, 85 and microsomal cytochrome, 11 among others.

“…Using PEDOT as a conductive polymer, the result showed a limit of detection of 0.07 nM. In a different approach [92], GCE modified with o-PD was electropolymerized with multifunctional nanomaterials, zinc oxide nanoparticles (ZnO NPs), and graphene platelets to create the MIP. This MIP was evaluated in real wastewater samples, and exhibited higher sensitivity than other approaches used for the detection of 4-CP, with a limit of detection of 40 nM and a linear range of 2.0 × 10 2 -1.7 × 10 5 nM.…”

Application of Molecularly Imprinted Polymers in the Analysis of Waters and Wastewaters

The increase of the global population and shortage of renewable water resources urges the development of possible remedies to improve the quality and reusability of waste and contaminated water supplies. Different water pollutants, such as heavy metals, dyes, pesticides, endocrine disrupting compounds (EDCs), and pharmaceuticals, are produced through continuous technical and industrial developments that are emerging with the increasing population. Molecularly imprinted polymers (MIPs) represent a class of synthetic receptors that can be produced from different types of polymerization reactions between a target template and functional monomer(s), having functional groups specifically interacting with the template; such interactions can be tailored according to the purpose of designing the polymer and based on the nature of the target compounds. The removal of the template using suitable knocking out agents renders a recognition cavity that can specifically rebind to the target template which is the main mechanism of the applicability of MIPs in electrochemical sensors and as solid phase extraction sorbents. MIPs have unique properties in terms of stability, selectivity, and resistance to acids and bases besides being of low cost and simple to prepare; thus, they are excellent materials to be used for water analysis. The current review represents the different applications of MIPs in the past five years for the detection of different classes of water and wastewater contaminants and possible approaches for future applications.
