TI  - CuO nanoleaf and beta-cyclodextrin functionalized reduced graphene oxide: a highly

AB  - Chlorophenols are considered priority pollutants and are harmful to humans and 
      the environment; consequently, sensitive, and selective detection of 
      chlorophenols is very significant. In the present article, a glassy carbon 
      electrode was modified by copper oxide nanoleaves, beta-cyclodextrin, and reduced 
      graphene oxide through an electrostatic self-assembly method (CuO 
      NLs-beta-CD-rGO-GCE) and successfully utilized for the selective and sensitive 
      detection of 2-chlorophenol (2-CP) and 2,4-dichlorophenol (2,4-DCP). The modified 
      electrodes were characterized by using SEM, EDX, ATR-FTIR, CV, and EIS. The 
      electrochemical behaviour of 2-CP and 2,4 DCP on different modified electrodes 
      was investigated by cyclic voltammetry whereas differential pulse voltammetry was 
      used for the quantitative determination of chlorophenols. Under the optimized 
      conditions, the anodic peak current displayed a good linear relationship to 
      concentration in the range of 5 to 50 muM for 2-CP and 5 to 30 muM for 2,4-DCP, 
      with detection limits of 0.22 nM and 0.52 nM, respectively. Moreover the proposed 
      sensor exhibited good reproducibility, high sensitivity, and long term stability. 
      To further study the practical applicability of the newly developed sensor, the 
      modified electrode was successfully used to determine 2-CP and 2,4-DCP in a water 
      sample with good recovery.
