Here, Pd nanoparticles and poly(taurine) film was prepared on the glassy carbon electrode surface (Pd/Poly(TAU)/GCE) by the rapid electrochemical technique. The proposed composite surface was characterized by scanning electron microscopy(SEM), X‐ray photoelectron spectroscopy(XPS) and electrochemical impedance spectroscopy(EIS). Enhanced electron transfer ability and higher electroactive surface area were achieved at Pd/Poly(TAU)/GCE as compared to the bare GCE and polymer film electrode. The new and highly stable Pd/Poly(TAU)/GCE was employed for the individual and simultaneous determination of hydroquinone and catechol which were environmentally toxic. Under the optimized conditions, HQ and CC were individually determined by using the differantial pulse voltammetry in the linear ranges of 0.008–100 μM and 0.001–100 μM with the detection limits of (LOD) 2.1 nM and 0.68 nM, respectively. In case of simultaneous determination, LODs were found as 10 nM and 0.88 nM for HQ and CC, respectively. The content of both analytes in the real sample analysis was evaluated in the river water and tap water successfully.

“…In our previous work, hydroquinone and catechol were determined on a PEDOT modified electrode, which showed a higher sensitivity and selectivity. 45 In this work, superconductive carbon black (SCB), owing to its superior conductivity, large specific surface area, high stability and better integration, was selected as a functional incorporation component to prepare a PEDOT-SCB composite film modified gold electrode. [46][47][48] To the best of our knowledge, there has been no report on the fabrication and application of a PEDOT-SCB modified Au electrode for the electrocatalytic oxidation and determination of AA.…”

A new composite film-modified electrode was prepared by the electropolymerisation of poly(3,4-ethylenedioxythiophene) (PEDOT) and superconductive carbon black (SCB) on a gold electrode. The PEDOT-SCB/Au electrode exhibited excellent ability towards the electrocatalytic oxidation of ascorbic acid, in terms of a 480 mV shift of the oxidation potential in the negative direction, and a dramatically enhanced oxidation current. Under the optimum conditions, the amperometric detection of ascorbic acid provided a wide linear detection range from 1.0 × 10 -7 to 8.0 × 10 -4 M, and a detection limit of 5.0 × 10 -8 M (S/N = 2) as well as good reproducibility and stability.

“…[10][11][12][13][14][15][16] Among these methods, the electrochemical approach has emerged as a most promising detection technique due to its simplicity, cost effectiveness, ease of handling, selectivity and high sensitivity. 17,18 Various novel electrode materials have been employed for the electrochemical detection of HQ. Previously, Qi et al prepared a novel S,N doped 3D graphene for the sensing of phenol derivatives.…”
