Abstract

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. Graphical abstract
