|Abstract:||We are introducing electrochemical sensor for the determination of lead (II) ions in aqueous medium based on the immobilization of dithizone over the porous silicon. The porous structure formation is characterized by photoluminescence spectroscopy further supported by Raman spectroscopy and scanning electron microscope. Scanning electron microscope and Atomic force microscope studies shows the globular structure covers the porous silicon surface, which further chemically confirmed through FTIR and cyclic voltammetry. The electrode response towards the Pb2+ ions is observed through the cyclic voltammetry and their detection limit ranges from 0.1 µg/ml to 10 mg/ml is done by differential pulse voltammetry. These strategies open up exciting new diagnosis for the development of sensing concepts and sensory device in the field of environment.|
