Abstract

A chelating ion-exchange resin (1-hydroxy-2-naphthaldoxime-formaldehyde polymer) containing nitrogen and oxygen donor atoms was prepared and characterized. The resin behaves as a selective chelating ion exchanger for some metal ions. The poly(vinyl chloride)-based membrane electrode of the resin shows a Nernstian response for Ni²⁺ over a wide concentration range (2.94 × 10³–5.87 × 10³ mg dm⁻³) between pH 3.0 and 7.5. The electrode is found to possess adequate stability and specific selectivity with a response time of 10 s. The sensor can also be used in a partially non-aqueous medium having a 35% (v/v) non-aqueous content.

Theoretical and experimental approaches to the preparation, characterization and application of a newly synthesized mesoporous Zn-MOF as a selective ionophore for Ni(II) ion in carbon paste electrode matrix
2023, Journal of Molecular Structure
A novel carbon paste electrode (CPE) chemically modified with a newly synthesized Zn-metal organic framework (Zn-MOF) was synthesized for Ni(II) ion determination with impressing enhancement in sensitivity and selectivity over the preceding studies. Due to their electrocatalytic and substantial surface area criteria, MOFs are a reasonably new category of fascinating materials for precise electrochemical detection. Under the sonication condition, a novel Zn-MOF depending on a Schiff base ligand in nano size was synthesized, and it was characterized using different characterization methods such as powdered X-ray diffraction (PXRD), FT-IR, BET surface area, contact angle and scanning electron microscope (SEM) combined with energy dispersive X-ray analyzer (EDX). The BET surface area and contact angle measurement techniques results were 2901.08 m² g⁻¹ and 143.49°, respectively, for the synthesized MOF. It was concluded that under the ideal experimental circumstances, the produced Zn-MOF can extract and sense nickel ions from aqueous solution selectively. Several crucial factors were optimized to gain the ultimate electrochemical response. Response mechanism was proved by the aid of study of morphological change and functional groups chemical shifts. Ultimately, a calibration with a Nernstian slope of 28.75 mV decade⁻¹ over linear concentration limits from 5.0 × 10⁻⁸ to 1.0 × 10⁻¹ mol L⁻¹ (R² = 0.9990) and detection limit of 5.0 × 10⁻⁸ mol L⁻¹ was obtained. The relative standard deviations and recovery ranges of the proposed approach for determining the Ni(II) ion in various water and food tests (n = 5) were 0.94–2.35% and 97.0–104%, respectively.

Although, there is no any flexible sensor has been previously reported for on-site detection of Ni (II) ions, however, a comparative study between the new fabricated AFCC-PNP-based sensor and other types of sensors reported for Ni (II) ions estimation has been constructed to reflect the preference of the newly fabricated AFCC-PNP-based flexible sensor over the other reported ones. As pronounced in Table 7, in addition to its flexibility and bending properties (Fig. S1), the fabricated AFCC-PNP-based sensor displayed a promising performance superior to the other reported Ni (II) ions selective sensors (Table 7) in terms of achieving Nernstian slope value of 29.5 mV decade−1 over wider concentration range of 1.0 × 10−5 – 1.0 × 10−1 mol L−1 [63,64,66,69] with a lower detection limit (2.7 × 10−6 mol L−1) [63,64,66,69] as indicated in Table 7. Furthermore, the fabricated AFCC-PNP-based sensor showed a rapid performance for Ni (II) ions determination with faster response time of 6 s [63–69] over wider pH range of 2.0–8.0 compared to the other reported sensors [63–65,67–69].
Herein, for the first time, an innovative and sensitive flexible sensor for efficient potentiometric monitoring of Ni (II) ions has been designed and developed. The developed flexible sensor is constructed from highly porous activated flexible carbon cloth decorated with nitrogen and spherical porous carbon nanoparticles derived from low-cost cotton doped with polypyrrole nanoparticles via simple carbonization-activation process followed by dip-coating in membrane cocktail containing 2D Ni-MOF nanosheets as an electroactive material. The developed flexible sensor affords rapid, accurate and stable response for the Ni (II) ions monitoring at its trace level in the biological fluids including human saliva and sweat samples in addition to tap water as an environmental sample without any preconditioning steps over pH range of 2–8 with detection limit of 2.7 × 10⁻⁶. Additionally, the flexible sensor shows good antibacterial properties against both of Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli) bacteria presenting safe handling for human skin as a flexible sensor for wearable system applications. This study presents a forward step for the fabrication of a wearable sensor for rapid onsite monitoring of Ni (II) ions in biological and environmental samples.
Chronopotentiometric and electroanalytical studies of Ni(II) selective polyaniline Zr(IV) molybdophosphate ion exchange membrane electrode

The exclusion of co-ions from the membrane phase, size of the hydrated radii of the counter ion, interstices of the membrane phase suggests the selectivity of membrane for a particular ionic species (counter ion). A large number of ion exchange membranes have been prepared by organic resins [4], inorganic precipitate [5], organic–organic composite [6,7], organic–inorganic composites [8] and their applications in different fields are available in literature. Ion exchange membranes that are selective for a particular ionic species is the demand of the researchers who are engaged to develop potable chemical and vapor sensing devices in order to monitor indoor and outdoor environment.
Polyaniline Zr(IV) molybdophosphate (PAZMP) was synthesized by sol–gel method and its ion exchange capacity (IEC) was determined as 2.50 meqg⁻¹. On the basis of distribution co-efficient (K_d values) the material was selective for Ni(II). The Ni(II) selective membrane was prepared (IEC 0.65 meqg⁻¹) to fabricate Ni(II) selective membrane electrode with its linear potential response in the concentration range of 1 × 10⁻⁷ M–1 × 10⁻¹ M. The morphology and composition of the prepared PAZMP membrane were ascertained by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDX) respectively. The ion exchange mechanism through membrane was determined by chronopotentiometric studies using Nernst-Planck equation at 30 °C, 45 °C and 60 °C. As a result physical parameters such as self-diffusion coefficient (D₀), energy of activation (E_a) and entropy of activation (ΔS°) were calculated. The analytical utility of this electrode was established by employing it as an indicator electrode in potentiometric titration.
Development and characterization of a new nickel(II) ion selective optode based on 2-amino-1-cyclopentene-dithiocarboxylic acid
2011, Measurement: Journal of the International Measurement Confederation
A highly sensitive and selective optical membrane sensor was prepared for the determination of ultra trace amount of Ni²⁺ ions. The plasticized PVC membrane incorporating dibuthylphthalate and 2-amino-1-cyclopentene-dithiocarboxylic acid (ACDA) as a chromoionophore works on the basis of a cation-exchange mechanism and shows a significant absorbance signal change on exposure to acidic solution containing nickel(II) ion. The sensor displays a calibration response for Ni²⁺ ion over a wide concentration range of 3.1 × 10⁻⁸–8.0 × 10⁻³ M, and a response time of 3 min. In addition to high stability, reproducibility and relatively long working lifetime, the sensor possesses good selectivity for nickel(II) ion over several common diverse ions. The sensor was successfully applied to determine the traces of Ni²⁺ ion in some water samples.
Ni(II) selective sensors based on Schiff bases membranes in poly(vinyl chloride)
2008, Analytica Chimica Acta
The two nickel chelates of Schiff bases, 3-hydroxy-N-{2-[(3-hydroxy-N-phenylbutyrimidoyl)-amino]-phenyl}-N′-phenylbutyramidine (M₁) and bis-4-(ethyliminomethyl)naphthalene-1-ol (M₂), have been synthesized and explored as ionophores for preparing PVC-based membrane sensors selective to nickel ion. The influences of membrane compositions on the potentiometric response of the electrodes have been found to substantially improve the performance characteristics. The best performance was obtained with the electrode having a membrane composition (w/w; mg) of (M₁): PVC:NaTPB:CN in the ratio 5:150:5:150. The sensor shows a linear potential response for Ni²⁺ over a wide concentration range 1.6 × 10⁻⁷ to 1.0 × 10⁻² M with Nernstian compliance (30.0 ± 0.2 mV/decade of activity) within pH range 2.5–9.5 and a fast response time of 10 s. The sensor has been found to work satisfactorily in partially non-aqueous media up to 20% (v/v) content of methanol, ethanol, and acetonitrile and could be used for a period of 4 months. The analytical usefulness of the proposed electrode has been evaluated by its application in the determination of nickel in real samples. The practical utility of the membrane electrode has also been observed in the presence of surfactants.

2007, Talanta
PVC-based membranes of meso-tetrakis-{4-[tris-(4-allyl dimethylsilyl-phenyl)-silyl]-phenyl}porphyrin (I) and (sal)₂trien (II) as electroactive material with dioctylphthalate (DOP), tri-n-butylphosphate (TBP), chloronapthalene (CN), dibutylphthalate (DBP) and dibutyl(butyl) phosphonate (DBBP) as plasticising solvent mediators have been found to act as Ni²⁺ selective sensor. The best performance was obtained with the sensor having a membrane of composition of I: sodium tetraphenyl borate: PVC in the ratio 5:5:150. The sensor exhibits Nernstian response in the activity range 2.5 × 10⁻⁶ to 1.0 × 10⁻¹ M, performs satisfactorily over wide pH range (2–5.5) with a fast response time (∼8 s). The sensor was found to work satisfactorily in partially non-aqueous media up to 20% (v/v) content of methanol or ethanol and acetone and could be used over a period of 4 months. Potentiometric selectivity coefficients determined by matched potential method (MPM) indicate excellent selectivity for Ni²⁺ ions. The sensors could be used successfully in the estimation of nickel in different brand of chocolates and also as an indicator electrode in potentiometric titration.
