Electrodeposition of Porous Polyaniline Coating on an Etching Stainless Steel Wire as a Fiber for Solid-Phase Microextraction of Triclosan and Chlorophenols in Water Samples

Abstract:

A novel polyaniline (PANI) coating doped with perchlorate ions was prepared on a stainless steel (SS) wire by a three-electrode system. Before electrodeposition, the SS wire was etched by hydrofluoric acid to enhance its surface roughness. The prepared PANI-coated fiber was used for solid-phase microextraction (SPME) of 2-chlorophenol (2-CP), 2,4-dichlorophenol (2,4-DCP) and triclosan (TCS) in water samples followed by high-performance chromatography with UV detection (HPLC-UV). The extraction procedure was optimized. The proposed SPME-HPLC-UV method provided a wide linear range. The limits of detection were 0.006 ng/mL for 2-CP, 0.005 ng/mL for 2,4-DCP and 0.04 ng/mL for TCS, respectively. It was successfully applied to the analysis of spiked surface water samples with the recoveries from 99.6% to 109%.
