• W2558175090 abstract "An electro-chemically active composite film containing the environmentally friendly surfactant sodium dodecyl sulfate (SDS) and poly(1-amino-9,10-anthraquinone) (PAAQ) is used as an electron transfer mediator in the electro-chemical oxidation of catechol. Compared with the bare platinum (Pt) electrode, the Pt/PAAQ-SDS modified electrode remarkably lowered the anodic peak potential of catechol, and increased the peak currents. The results obtained indicated that the activation energy for the electro-chemical oxidation of catechol at the polymer film was low (7.05 kJ mol -1 ). The influence of operational conditions on the response current of the catechol sensor was investigated. Studying the surface morphology of the modified electrode revealed a more porous structure due to the incorporation of the anionic surfactant on the PAAQ film. The modified electrode displayed a linear response range between 0.01 and 8.0 mM of catechol. The lower limit of detection was obtained to be 2.60 m M . The ability of the modified electrode was also examined for the electro-chemical detection of hydroquinone (HQ) with simplicity.
