“…When the modified electrode was immersed in a solution of potassium hexacyanoferrate (III), K 3 [Fe(CN) 6 ], a pair of redox peaks appeared at potential of 0.68 − 0.72 V attributed to the Fe II /Fe III pair in the complex Cu 2 [Fe(CN) 6 ] formed within the polymeric film. Several works reported the application of copper polymeric films in determination of sulfite and nitrite but problems with repeatability and control of the amount of copper deposited on the electrode surface limits its use . In this work, Cu(II)MA‐based copolymers are presented as excellent option to manufacture of GCE modified with copper polymer that allows to increase the amount of copper on the electrode surface, which could improve the sensibility, lifetime, repeatability, and precision of the electroanalytical method.…”

This work focuses on the synthesis of a new class of copolymer materials consisting of traditional vinyl monomers (essentially, vinyl acetate, ethyl acrylate, and methyl methacrylate) and copper (II) methacrylate (Cu(II)MA) intended to be used as surface modification agents in electrochemical quantifications of organic and inorganic analytes. Voltammetry assays showed that when deposited on glassy‐carbon electrode (GCE), Cu(II)MA‐based copolymers are very promising materials to be applied in electrochemical determinations, exhibiting high analytical signal in the oxidation and reduction peaks during quantification of potassium hexacyanoferrate (III) in comparison to a bare GCE, contributing to increase the effective electrode area. When employed for the determination of ascorbic acid, PVAcCu(II)MA/GCE exhibited performance similar to that of the bare GCE. Polymers characterizations showed that glass transition temperature of the Cu(II)MA‐based materials increased in approximately 10–20°C, as consequence of the copper present in molecular structure of the copolymer chains (bidentate bridging coordination mode). Energy‐dispersive X‐ray spectroscopy measurements of Cu(II)MA monomer and Cu(II)MA‐based copolymers showed strong characteristic peaks Kα and Kβ at 8.04 and 8.90 keV, respectively, with an average amount of copper of 99%. The performance of the Cu(II)MA‐based copolymers modified electrodes is strongly dependent on the amount of copper into the copolymer chains and consequently on the monomers conversion. © 2015 Wiley Periodicals, Inc.

Electroactive ion exchange materials (EIXMs) with unique electrochemically switched ion exchange function have been extensively applied in various fields including high value-added ion recovery, toxic ion removal, energy storage device and electrochimical ion sensor. In particular, the charge and discharge of EIXMs can be electrochemically controlled by external electric field or by redox agent while the charge balance is compensated via the ion exchange with electrolyte solution. To date, the discovered EIXMs mainly involve inorganic compounds with mixed-valence transition metals, organic conducting polymers and organic-inorganic hybrid materials. Compared with their bulk forms, nanostructured EIXMs have aroused considerable research interest recently owing to their unique properties such as larger surface area, better ion diffusion path and more excellent electron transfer property. In this article, the design principles and synthetic routes for the development of various nanostructured EIXMs and their applications in the fields of selective ion separation, supercapacitors and electrochemical ion sensors are reviewed. In addition, the main challenges and future prospects for the further development of high-performance EIXMs are discussed.

“…Compared with these techniques, electrochemical methods have significant advantages including high sensitivity, selectivity and low costs. However, only few reports are available on the development of sulphite sensors using transition MHCFs modified electrodes [36][37][38]. To the best of our knowledge, no reports are available on the sulfite sensors using rare earth MHCFs modified GCE.…”
