Synthesis and Voltammetric Determination of Pb(II) Using a ZIF-8-Based Electrode

Zeolite imidazole framework-8 (ZIF-8) was prepared by the hydrothermal process. The obtained ZIF-8 was a characteristic of X-ray-diffraction (XRD), transmission electron microscope (TEM), thermal gravity-differential thermal analysis (TG-DTA), and dynamic light scattering (DLS). The obtained ZIF-8 p...
