A facile method was developed for the synthesis of nitrogen ‐ doped porous carbon‐gold (NPCAu) hybrid nanocomposite. The NPCAu modified gold electrode has been prepared for the electrochemical determination of ultratrace mercury(II) in drinking water through square wave anodic stripping voltammetry (SWASV). Under optimized conditions, the NPCAu modified electrode shows a sensitive detection to Hg(II) ion present in concentrations of 0.001 ∼ 1 μM, with a detection limit of 0.35 nM (S/N=3), which was much lower than the guideline values in drinking water given by the World Health Organization.
