Title

Polythiophene Imprinted CeO2 Fluorescent Probe for Lead Detection in Tab Water Samples

Pages

  87-96

Abstract

 The development of real-time, highly sensitive, and selective, simple techniques for the detection of toxic Pb2+ in water was challenged. However, in this study, a highly efficient fluorescent probe based on Polythiophene Imprinted CeO2 nanocomposite for selective detection of Pb2+ ion was developed by polymerization method. The developed fluorescent probe was characterized by using powder X-ray diffraction (XRD), Fourier-Transform Infrared spectroscopy (FT-IR), and Scanning Electron Microscope (SEM). Upon binding to the Imprinted binding sites PT/CeO2 the Pb2+ interacts with the molecular orbital and their fluorescence is quenched via reverse photoinduced electron transfer which results in qualitative and quantitative detection. The factor affecting the detection system such as pH and concentration are optimized. Additionally, the PT/CeO2 fluorescent sensor exhibits high sensitivity with a Stern Volmer Quenching (KSV) value of 6. 39 × 103 M-1. The practical application of the sensor was also tested by spiking with different concentrations of Pb2+ ion solutions on tab water samples. The result indicates a good linear relation between FO/F and the spiked concentrations with the coefficient of regression R2 = 0. 99 (n = 3) and also confirms that the found values are agreed well with the spiked amount. The obtained amounts of lead metal ion concentrations in tap water were 15. 39 μ, M which exceeded the allowable limit as stated by WHO.
