“…All the linear equations, linear correlation coefficient (R 2 ), and detection limits were listed in Table SI (see in Supplementary Information). The detection limits of CAT and HQ on NanoAu/Poly(ABSA)/MWCNTs/GCE were close or smaller than those from most of literature reports 17,21,30,33,[40][41][42][43][44][45][46][47][48][49][50][51][52] (see Table I). The detection sensitivity of CAT and HQ on NanoAu/ Poly(ABSA)/MWCNTs/GCE by us was 16.53 and 17.68 μA•μM -1 •cm -2 respectively, much bigger than those from literature reports.…”

“…Chemically modified electrodes based on the modification of active materials on bare electrode can not only seperate CAT and HQ well but also improve their detection sensitivity, which are widely applied to construct electrochemical sensor for determining CAT and HQ simultaneously. [17][18][19] Carbon nanotubes (CNTs) are the nanomaterials with notable tensile strength, elasticity, catalytic property and chemical activity. 20,21 However, for CNTs modified electrode, CNTs are easy to fall off from electrode surface during multiple electrochemical measurements.…”

Gold nanoparticles/poly(p-aminobenzenesulfonic acid)/multi-walled carbon nanotubes modified glassy carbon electrode (NanoAu/Poly(ABSA)/MWCNTs/GCE) was prepared for electrochemically detecting catechol (CAT) and hydroquinone (HQ) by cyclic voltammetry (CV) and differential pulse voltammetry (DPV). Results showed that CAT and HQ were electrochemically seperated well, and the difference between oxidation peak potentials of CAT and HQ was 111 mV. The redox currents of CAT and HQ were significantly enhanced on NanoAu/PABSA/MWCNTs/GCE, as compared with on bare GCE. The oxidation peak current (Ipa) of 10 μM CAT was 0.24 μA, and there was almost no detected oxidation current response for 10 μM HQ on bare GCE. The Ipa values on NanoAu/Poly(ABSA)/MWCNTs/GCE increased to 11.3 times for CAT as compared with on GCE, 1.5 times for CAT and 2.5 times for HQ as compared with on MWCNTs/GCE. The linear range of CAT and HQ measurments on NanoAu/Poly(ABSA)/MWCNTs/GCE was 2 ~ 200 μM, and the limit of detection (LOD, S/N = 3) was 1.5 μM for CAT and 1.0 μM for HQ. This sensor showed high detection sensitivity for CAT (16.53 µA﹒µM–1﹒cm–2) and HQ (17.68 µA﹒µM–1﹒cm–2). The sensor had been applied for CAT and HQ measurement in lake water with satisfactory results.

“…The AuNPs [34] modified working electrode can provide more electro active sites and faster electron transfer rate, all of which contribute to enhance the sensitivity of the simultaneous determination of Hydroquinone and catechol. It is difficult to simultaneously determine catechol and hydroquinone due to their overlapping peaks at ordinary electrode [35].…”

Carbon nanomaterials (CNMs), especially carbon nanotubes and graphene, have been attracting tremendous attention in environmental analysis for rapid and cost effective detection of various analytes by electrochemical sensing. CNMs can increase the electrode effective area, enhance the electron transfer rate between the electrode and analytes, and/or act as catalysts to increase the efficiency of electrochemical reaction, detection, adsorption and removal are of great significance. Various carbon nanomaterials including carbon nanotubes, graphene, mesoporous carbon, carbon dots exhibited high adsorption and detection capacity. Carbon and its derivatives possess excellent electro catalytic properties for the modified sensors, electrochemical methods usually based on anodic stripping voltammetry at some modified carbon electrodes. Metal electrode detection sensitivity is enhanced through surface modification of working electrode (GCE). Heavy metals have the defined redox potential. A remarkable deal of efficiency with the electrochemical sensors can be succeeded by layering the surface of the working electrode with film of active electro-catalytic species. Usually, electro catalysts used for fabrication of sensors are surfactants, nano-materials, polymers, carbon-based materials, organic ligands and biomaterials.
