R-3 Repository

Rice University Research Repository

The Rice Research Repository (R-3) provides access to research produced at Rice University, including theses and dissertations, journal articles, research center publications, datasets, and academic journals. Managed by Fondren Library, R-3 is indexed by Google and Google Scholar, follows best practices for preservation, and provides DOIs to facilitate citation. Woodson Research Center collections, including Rice Images and Documents and the Task Force on Slavery, Segregation, and Racial Injustice, have moved here.

Electrochemical sensing of PFAS using gold nanoparticle functionalized electrodes

(2025-03-04) Villagran, Dino; Westerhoff, Paul; Calvillo Solis, Jonathan Josue; Wong, Michael; Rice University; Board of Regents, The University of Texas System; Arizona Board of Regents on Behalf of Arizona State University; United States Patent and Trademark Office

A method of electrochemical sensing includes providing an electrochemical sensor comprising a glassy carbon substrate and gold nanoparticles located on a surface of the glassy carbon substrate; and sensing electrochemically a compound selected from the group consisting of polyfluoroalkyl compounds or perfluoroalkyl compounds using the electrochemical sensor. PFOA quantification was performed by Square Wave Adsorptive Cathodic Stripping Voltammetry (SW-AdCSV) in test solutions with a 100-5,000 ppt concentration. The concentration has a linear relationship with the stripping current within this range. Analysis of tap and groundwater samples performed by additions method demonstrated precision and accuracy above 95%. These electrodes show stability throughout 200 cycles, and reproducibility across similarly prepared but different electrodes above 97.5%. Providing the electrochemical sensor can include providing at least one member selected from the group consisting of perfluoro-1-octanethiol (PFTO), 2,2,2-trifluoroethanethiol (TFET) or perfluorodecanethiol (PFDT) on the surface of the glassy carbon substrate.
