Abstract: In this study, manganese dioxide decorated typha tassel carbonized material was prepared. The pyrolysis of the carbonaceous material occurred in a tube furnace at 800 °C under nitrogen atmosphere. MnO2 nanoparticles on typha tassel (CT) were synthesized with sol–gel method. The final product was denoted as MTT electrode (MnO2-CT). The carbonaceous material was characterized with infrared spectroscopy, X-ray photoelectron spectroscopy, scanning electron microscopy and X-ray diffraction methods. Electrode usability performance of the material was examined via electrochemical techniques. An electrochemical method was developed with stripping voltammetry for the analysis of heavy metals such as Pb2+ and Cd2+ on the MCT electrode. The linear equations for Cd2+ and Pb2+ were computed. The limit of detection (S/N = 3) was 0.05 μg/L for Cd2+ and 0.01 μg/L for Pb2+ within the range of 0.5–50 μg/L and 0.2–50 μg/L, respectively. The method was successfully applied to the simultaneous determination of Cd2+ and Pb2+ in tap water and milk samples.
