چکیده انگلیسی
In this work, a sensitive and reliable electrochemical platform was developed for catechol (CC) and hydroquinone (HQ) individual and sensitive simultaneous detection. Due to the outstanding advantages of low cost, excellent flexibility, large surface area, and good conductivity, an exfoliated graphite paper (EGP) was used as a supported electrode for gold nanoparticles (AuNPs) electrodeposition to fabricate a sensor (AuNPs/EGP). Scanning electron microscope and cyclic voltammetry results revealed that AuNPs/EGP was successfully prepared with multi-layered structure and enhanced electron transfer ability. Under the optimized conditions, the sensor showed wide linear range for CC and HQ detection of 5.0 Â ÃÂ 10â7 - 1.0 Â ÃÂ 10â4 mol/L and 7.0 Â ÃÂ 10â8 - 1.0 Â ÃÂ 10â4Â mol/L with limitation of detection (S/NÂ =Â 3) of 4.13Â ÃÂ 10â8Â mol/L and 2.73 Â ÃÂ 10â8 mol/L, respectively. And the proposed sensing platform was successfully applied to the simultaneous determination of CC and HQ in real samples of three kinds of water with reliable recovery. The low cost, facile preparation, and attractive electrochemical performances made the graphite paper based sensor promise perspectives in the field of electroanalysis.
