A sensitive and selective electrochemical sensor for catechol (CC) using a multi-walled carbon nanotubes-poly(1,5diaminonaphthalene) composite modified glassy carbon electrode (MWCNTs/p-DAN/GCE) is reported. The surface features of the modified electrodes were characterized by a scanning electron microscope (SEM), and an energy-dispersive X-ray spectrometer (EDX). The electrochemical behavior was investigated using cyclic voltammetry (CV). The cyclic voltammogram of the modified electrode is characterized by a remarkable increase in the redox peak currents for CC, which indicates that MWCNTs/p-DAN film enhances significantly the electrocatalytic response toward CC. The effects of different parameters, such as pH, accumulation time, amount of MWCNTs, and scan rate on the response of the developed sensor were investigated. The analytical performances were also investigated using differential pulse voltammetry (DPV). The optimized MWCNTs/p-DAN/GCE based CC sensor exhibited a linear response over a range of 2.0 × 10 −8 to 1.3 × 10 −4 M with a lower limit of detection (LOD) of 1.0 × 10 −8 M (S/N = 3). Moreover, the developed CC sensor is characterized by high sensitivity, excellent repeatability, and excellent selectivity. The proposed sensor showed high selectivity for catechol relative to most potential interferents particularly hydroquinone (HQ) and resorcinol (RC), typical interfering agents. The developed sensor was successfully applied for the determination of CC in real water samples with satisfactory recovery results.

Due to their comparable electrical properties, pencil graphite electrodes (PGE) have become a more popular electrode in electrochemical applications than traditional carbon electrodes, mostly because of their affordability and availability, which allows for disposable applications. Both cyclic voltammetry (CV) and chronoamperometry (CA) techniques were used to develop a new disposable modified pencil graphite electrode based on the electropolymerization of 1,5-diaminonaphthalane (1,5-DAN). Characterization results confirmed that the modified p-1,5-DAN/PGE(CV) sensor showed significwntly enhanced sensitivity and lower resistivity than the bare and p-1,5-DAN/PGE(CA) sensor, therefore, it was used for the sensitive and selective voltammetric determination of flufenamic acid (FFA). Under the optimum experimental conditions, the p-1,5-DAN/PGE(CV) sensor showed limits of detection and quantitation of 4.97  10-10 (0.14 ng ml-1) and 1.66  10-9 M (0.47 ng ml-1), respectively, applying square wave anodic stripping voltammetry method. The p-1,5-DAN/PGE(CV) sensor also exhibits good accuracy, repeatability, storage stability, and selectivity for detecting FFA in biological fluids. These results confirms that the developed p-1,5-DAN/PGE(CV) sensor is more sensitive to measuring FFA in biological fluids, pharmaceutical formulations, and pharmacokinetic studies compared with the previous electrochemical sensors.

Chemical Response of Nanocomposite Membranes of Electroactive Polydiaminonaphthalene Nanoparticles to Heavy Metal Ions

Poly(1,5-diaminonaphthalene) (P15DAN) is a novel multifunctional but intractable polymer, from which it is difficult to preparing a large uniform membrane directly. A unique electroactive composite membrane was facilely prepared by dropcasting the dispersion of the P15DAN nanoparticles in 0.1% poly(vinyl alcohol) aqueous solution. The cyclic voltammogram of an electrode modified by the nanocomposite membrane strongly depends on the potential sweeping rate and pH value of the electrolyte solution. The anodic/cathodic peak currents rise linearly with increasing the sweeping rate, but decline with increasing the pH value. The redox and coordination sensitivity of the nanocomposite membrane to heavy metal ions including silver, mercury, and copper ions was explored by open-circuit potential and cyclic voltammetry techniques. The results indicate that the three ions are all spontaneously and non-electrochemically reduced by the P15DAN and then adsorbed on the membrane surface upon contacting each other, but the reduction extent of silver(I) and mercury(II) ions is much higher than that of copper(II) ion on the basis of the variation of the open-circuit potential. The nanocomposite membrane exhibits stable electroactivity, dense membrane structure, long cyclic lifetime, and strong adhesion onto the electrode, which features are different from those of pure electrosynthesized P15DAN membrane-modified electrode. The cyclic voltammetry of the nanocomposite membrane that was previously soaked in silver and copper ion solutions reveals strong oxidation and weak reduction peaks, while the cyclic voltammogram of the nanocomposite membrane previously soaked in mercury ion solution displays a weak oxidation but no reduction peak. It could be inferred that the silver(0) and copper(I) ions non-electrochemically reduced during soaking stages are more electrochemically oxidized than the reduced mercury(I) which has already been strongly coordinated with P15DAN. The nanocomposite membrane method proposed in this study enables fabrication of an electrode functionalized by insoluble electroactive nanomaterials which could not be densely and thinly electrodeposited or solution cast.
