EPI is also known as adrenaline, is a medication and hormone. Biowaste eggshell-derived CaO, obtained through calcination, serves as a sustainable support matrix for WO₃ and Cu, enhancing its porous hierarchical structure to prevent particle agglomeration and increase active sites. The nanocomposite was analyzed using various techniques including fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy coupled with energy-dispersive X-ray spectroscopy, transmission electron microscopy, atomic force microscopy, and Raman spectroscopy. The WO₃/Cu:CaO was blended homogeneously with carbon paste electrode (CPE) for the sensitive detection and quantification of EPI in pH 7.4 phosphate buffer saline (PBS). The charge transfer resistance and other electrochemical impedance spectroscopy data of bare and modified CPE were used for identifying the efficiency of the fabricated electrode. Electrochemical studies evidenced a detection limit of 0.00246 µM (S/N = 3) with a linearity range 0.1–1000 µM. In the presence of metal ions and interfering excipients, the synthesised sensor’s selectivity was examined. The real-sample analysis of human serum, urine, and breast milk achieved 98–99 % recovery values. The good recovery values, excellent reproducibility make WO₃/Cu:CaO/CPE a suitable for analytical tool for non-enzymatic EPI detection at the nanolevel. The WO₃/Cu:CaO nanocomposite modified CPE holds significant promise for future development of portable, low-cost, point-of-care devices to repurpose into high-performance sensing materials for rapid detection of EPI in biomedical field.</div></div>","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"155 ","pages":"Pages 710-722"},"PeriodicalIF":5.9,"publicationDate":"2026-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146147210","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}

The capture of Ag(I) by S-CTP is a fast chemisorption process, with a maximum adsorption capacity of 1675 mg/g. The adsorption of Ag(I) ions by S-CTP is spontaneous, and there is an increase in adsorption efficiency with increasing temperature.
