“…Other metal-sensitive sensors based on different polymeric membrane ion-selective electrodes incorporating ionophores, sensitive to different cations, have been widely reported in the literature [ 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 ]. Most of these sensors exhibit a near-Nernstian or Nernstian response to the different cations studied.…”

In this study, lignosulfonate (LS) from the acid sulfite pulping of eucalypt wood was used to synthesize LS-based polyurethanes (PUs) doped with multiwalled carbon nanotubes (MWCNTs) within the range of 0.1–1.4% w/w, yielding a unique conducting copolymer composite, which was employed as a sensitive material for all-solid-state potentiometric chemical sensors. LS-based PUs doped with 1.0% w/w MWCNTs exhibited relevant electrical conductivity suitable for sensor applications. The LS-based potentiometric sensor displayed a near-Nernstian or super-Nernstian response to a wide range of transition metals, including Cu(II), Zn(II), Cd(II), Cr(III), Cr(VI), Hg(II), and Ag(I) at pH 7 and Cr(VI) at pH 2. It also exhibited a redox response to the Fe(II)/(III) redox pair at pH 2. Unlike other lignin-based potentiometric sensors in similar composite materials, this LS-based flexible polymeric membrane did not show irreversible complexation with Hg(II). Only a weak response toward ionic liquids, [C2mim]Cl and ChCl, was registered. Unlike LS-based composites comprising MWCNTs, those doped with graphene oxide (GO), reduced GO (rGO), and graphite (Gr) did not reveal the same electrical conductivity, even with loads up to 10% (w/w), in the polymer composite. This fact is associated, at least partially, with the different filler dispersion abilities within the polymeric matrix.

Reported herein is the synthesis of electrochemically prepared graphene with dopamine (DA) functionalization and its application for the electrochemical detection of DA in presence of serotonin (5-HT). Graphene oxide-DA (GO-DA) resulted from the condensation reaction of GO and DA. It was characterized via several instrumental methods. The electrochemical reduction of GO-DA (ERGO-DA) has been employed for the electrochemical detection of DA without and with 5-HT. The electrochemical detection of DA has been verified through cyclic voltammetry, differential pulse voltammetry, and amperometric techniques in a 0.1 M phosphate buffer saline (PBS, pH 7.4). The influence of the accumulation time and pH of the PBS at ERGO-DA modified electrode for DA oxidation has been investigated. The interference has also been performed using interfering substances such as 5-HT, glucose, ascorbic acid, H 2 O 2 , and uric acid. The detection limit and linear range of DA have been calculated as 0.04 μM and 0.5-100 μM, respectively, (where s/n = 3) at the ERGO-DA modified electrode. The real sample analysis has done without any difficulty and this biosensor can be used up to 10 days.

“…in the market. Researchers have recently reported the new ion selective membrane sensors to detect Cu 2+ , Ag + and Mn 2+ ions (Jeong et al, 2010;Seo et al, 2010;Aghaie et al, 2010). However, much more studies are needed in developing ion selective electrodes to detect heavy metal ions which are poisonous even at very low concentrations.…”

Ni 2+ ion-selective electrode (Ni-ISE) based on plasticized poly(vinyl chloride) (PVC) membrane with 25, 26, 27 tri propoxy 28, Amino 5, 11, 17, 23-tetra-tert-butyl-calix[4]arene as ionophore and dibutyl phthalate (DBP) as plasticizer was designed and constructed. The Ni-ISE showed a linear reply in the concentration range of 1.0 × 10-1 to 1.0 × 10-4 M with slope of 29.3 ± 0.5 mV/decad. The Ni-ISE response time was ≤ 6 s and was used for two months with no deviation in the pH range 4 to 9. The best performance was obtained with a membrane composition of 30% PVC, 62% DBP, 3% 25, 26, 27-tripropoxy-28, amino 5, 11, 17, 23-tetra-tert-butyl-calix[4]arene and 5% potassium tetrakis[p-cholorophenyl]borate (KTpClPB). Its detection limit was 1.0 × 10-5 M. The selectivity coefficients , for different cations were calculated by the matched potential method (MPM). The scanning electron microscopy (SEM) of the Ni-ISE's membranes showed some morphological changes during its life span, probably due to both the reaction between the Ni 2+ ion and / or less of the membrane parts by permeation.
