Abstract :
In the present study, lead titanate nano-sized powders were synthesized using citric acid gel method. The nanopowders were
characterized using X-ray diffraction (XRD) and scanning electron microscopy (SEM). Then, a nanocomposite system based
on lead titanate nanopowders and carbon paste electrode (CPE) was designed and applied for determination of pentoxifylline
(PTX). The prepared nanostructured electrode exhibited voltammetric responses with high sensitivity and selectivity for PTX
and a detection limit of 2.1 nM was achieved. Finally, the proposed method was used for analysis of PTX in environmental
and biological samples with satisfactory results.
