Abstract

N′-[1-(Pyridin-2-yl)ethylidene]benzenesulfonohydrazide (PEBSH) was synthesized via a simple condensation of 2-acetyl pyridine and benzene sulfonyl hydrazide in very good yield and crystallized in methanol. The characterization of title compound were accomplished using highly sophisticated spectroscopic techniques like, UV/VIS, IR, ¹H-NMR and ¹³C-NMR. Finally the structure was determined with single crystal X-ray diffraction techniques for its further usage in detection of cations. Then a thin-layer of PEBSH onto flat-silver electrode (AgE) is deposited with conducting coating agents to fabricate a sensitive and selective Hg²⁺ ions sensor in short response time in phosphate buffer phase. The fabricated cationic-sensor is also exhibited higher sensitivity, large-dynamic concentration ranges, long-term stability, and improved electrochemical performances towards mercury ions. The calibration plot is linear (r² = 0.9799) over the large Hg²⁺ concentration ranges (0.1 nM to 1.0 mM). The sensitivity and detection limit is ∼2.1897 μA mM cm⁻² and ∼0.063 nM (signal-to-noise ratio, at a SNR of 3) respectively. This novel effort is initiated a well-organize way of efficient cationic sensor development with conducting binder deposited flat-electrode for toxic pollutants in environmental and health-care fields in large scales.
