AB  - Mercuric ion (Hg(2+)) in aqueous media is extremely toxic to the environment and 
      organisms. Therefore, the ultra-trace electrochemical determination of Hg(2+) in 
      the environment is of critical importance. In this work, a new electrochemical 
      Hg(2+) sensing platform based on porous activated carbon (BC/Cu(2)O) modified 
      with cuprous oxide was developed using a simple impregnation pyrolysis method. 
      Differential pulse anodic stripping voltammetry (DPASV) was used to investigate 
      the sensing capability of the BC/Cu(2)O electrode towards Hg(2+). Due to the 
      excellent conductivity and large specific surface area of BC, and the excellent 
      catalytic activity of Cu(2)O nanoparticles, the prepared BC/Cu(2)O electrode 
      exhibited excellent electrochemical activity. The high sensitivity of the 
      proposed system resulted in a low detection limit of 0.3 ng.L(-1) and a wide 
      linear response in the ranges from 1.0 ng.L(-1) to 1.0 mg.L(-1). In addition, 
      this sensor was found to have good accuracy, acceptable precision, and 
      reproducibility. All of these results show that the BC/Cu(2)O composite is a 
      promising material for Hg(2+) electrochemical detection.
