Preparation of Glassy Carbon Electrode Modified with Polymeric Meso–Tetrakistetrabromo Thienylporphyrin for Determination of Cadmium and Lead by Anodic Stripping Voltammetry

The use of a glassy carbon electrode modified with polymeric meso–tetrakistetrabromothienyl porphyrin (TBrTP) to determine Pb(II) and Cd(II) is reported. TBrTP was prepared by electrochemical polymerization in acetonitrile. Using SWASV, variables like number of cycles on the electropolymerization, p...
