Study on successfully fabricated to form a new electrode nano flower-shaped platinum on glassy carbon electrode and evaluated the morphological structure composition electrochemical properties electrochemically active surface area of fabricated electrodes by modern analytical methods. 2. The optimal conditions were determined by the univariate method and the modeling method - experimental optimization for simultaneous determination of Cd2 and Pb2 on PtNFs GC electrodes by differential pulse anodic stripping voltammetry. 3. The Cd2 and Pb2 analysis procedures have been developed and evaluated using the manufactured PtNFs GC electrode with good repeatability trueness high accuracy wide linear range low detection limit.
