Abstract : 4-(3-(thiophen-2-yl)-9H-carbazol-9-yl) benzaldehyde (TPCBZ) was synthesized under microwave irradiation with auto generated pressure (at 130.0 degrees C) and characterized by H-1 NMR, C-13 NMR, Mass and FTIR spectroscopy, thin-layer chromatography (TLC), and elemental analyses. Here, a thin-layer of TPCBZ onto glassy carbon electrode (GCE) is fabricated with conducting coating agents (5% nafion) to fabricate a selective and selective Cu2+ sensor in short response time in phosphate buffer phase. The fabricated sensor (TPCBZ/Nafion/GCE) is exhibited higher sensitivity, large-dynamic concentration ranges, long-term stability, and improved electrochemical performances towards TPCBZ-conjugated copper complex for selective Cu2+ sensor. The calibration plot is linear (r(2): 0.9979) over the large Cu2+ ions concentration ranges (1.0 nMe1.0 mM). The sensitivity and detection limit is similar to 1.12974 mu Acm(-2) mu M-1 and similar to 0.84 +/- 0.02 nM (signal-to-noise ratio, at a SNR of 3) respectively, which is calculated from the slope of the calibration plot. This novel effort is initiated a well-organize way of efficient cationic sensor improvement with carbazide for heavy metallic pollutants in environmental and health-care fields in large scales.
