AB  - In this paper, a simple strategy was proposed for the analysis of catechol by a 
      carbon paste electrode (CPE) modified with graphene oxide-third generation of 
      poly(amidoamine) dendrimer (GO/G3-PAMAM) nanocomposite and ionic liquid (IL). The 
      synthesis of GO-PAMAM nanocomposite was confirmed using X-ray diffraction (XRD), 
      energy-dispersive X-ray spectroscopy (EDS), field emission scanning electron 
      microscopy (FE-SEM), and Fourier transform infrared spectroscopy (FT-IR) 
      techniques. The prepared modified electrode (GO-PAMAM/ILCPE) exhibited good 
      performance to detect catechol with a notable decrease in overpotential and 
      increase in current compared with an unmodified CPE. Under optimum experimental 
      conditions, GO-PAMAM/ILCPE electrochemical sensors indicated a lower limit of 
      detection (LOD) of 0.034 muM and a linear response in the concentration range of 
      0.1 to 200.0 microM for the quantitative measurement of catechol in aqueous 
      solutions. In addition, GO-PAMAM/ILCPE sensor exhibited an ability to 
      simultaneously determine catechol and resorcinol. It can be found that catechol 
      and resorcinol could be completely separated on the GO-PAMAM/ILCPE with the 
      differential pulse voltammetry (DPV) technique. Finally, a GO-PAMAM/ILCPE sensor 
      was utilized to detect catechol and resorcinol in water samples with recoveries 
      of 96.2% to 103.3% and relative standard deviations (RSDs) of less than 1.7%.
