Analytical Methodology for Determination of Nonsteroidal Anti‐Inflammatory Drugs in Water Samples Using Polyaniline‐Silica Doped With Hydrochloric Acid as a Novel Extractor Phase in Thin Film Solid Phase Microextraction

Journal of Applied Polymer Science, Journal Year: 2025, Volume and Issue: unknown

Published: March 18, 2025

ABSTRACT A novel analytical methodology was developed in this study for the determination of four nonsteroidal anti‐inflammatory drugs, including aspirin, naproxen, ibuprofen, and mefenamic acid water samples using high‐performance liquid chromatography‐diode array detection. The thin film solid‐phase microextraction technique employed, coupled with a 96‐well plate sampling system, polyaniline‐silica doped hydrochloric used as extractor phase. optimized conditions were obtained through univariate multivariate approaches, optimum extraction 1.5 mL sample, pH 3, without salt addition, 300 μL acetonitrile. Calibration curves spiked ultrapure water; linear ranges from 15 to 500 μg L −1 , coefficients higher than 0.9957. Detection quantification limits 4.55 respectively. relative recoveries varied 81% 117% river sample at three different concentration levels each analyte. intraday ( n = 3) interday 9) precision values ≤ 8% 15%,
