Composites (GPA and GPA-PVPy) are characterized using field-emission scanning electron microscopy, X-ray diffraction, Raman spectroscopy, X-ray photoelectron spectroscopy, and thermogravimetric analysis. GPA and GPA-PVPy composites were coated on a glassy carbon (GC) electrode and investigated by cyclic voltammetry to verify their sensitivity towards Cif in the presence of UA as a major interference. Electrochemical impedance spectroscopy was used to estimate the electron transfer rate of composite electrodes.</div></div><div><h3>Significant Findings</h3><div>Using GPA-PVPy/GC electrode, similar concentrations of UA and Cif (10 – 310 μM) were simultaneously detected in a human urine sample with excellent sensitivity (0.007 μAμM<sup>-1</sup> (UA) and 0.0048 μAμM<sup>-1</sup> (Cif)) and low limit of detection (4.37 μM (UA) and 9.0 μM (Cif)), respectively showing its applicability in medical analysis.</div></div>","PeriodicalId":381,"journal":{"name":"Journal of the Taiwan Institute of Chemical Engineers","volume":"172 ","pages":"Article 106103"},"PeriodicalIF":5.5,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143747355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
