Abstract

ABSTRACT: Novel hybrid material was prepared by adding slurries of poly( N -methylaniline) and cerium tungstate [Ce2 (WO4 )3 ] into a conical flask contained dispersed carbon nanotubes. It was characterized by scanning electron microscope, X-ray diffraction, Fourier transform infrared spectroscopy, and thermogravimetric analysis. Electrical conductivity of poly( N -methylaniline)-Ce2 (WO4 )3 @carbon nanotube samples was determined using four-probe method. The thin layer of poly( N -methylaniline)-Ce2 (WO4 )3 @carbon nanotube was fabricated onto glassy carbon electrode for a selective Cd 2+ ion sensor. The calibration plot is linear ( r 2 = 0.9917) over the large Cd 2+ concentration ranges (1.0 nM–1.0 mM). The sensitivity, detection limit is ∼5.138 µA µM −1 cm −2 and ∼0.11 nM (signal-to-noise ratio, at a SNR of 3), respectively. GRAPHICAL ABSTRACT:
