RT info:eu-repo/semantics/article T1 Determination of uric acid in synthetic urine by using electrochemical surface oxidation enhanced Raman scattering A1 Hernández Muñoz, Sheila A1 Perales Rondon, Juan Víctor A1 Heras Vidaurre, Aránzazu A1 Colina Santamaría, Álvaro K1 Spectroelectrochemistry K1 Electrochemistry K1 Raman K1 EC-SOERS K1 Química analítica K1 Chemistry, Analytic AB In this work, a new and easy methodology to determine uric acid in relevant samples using Raman spectroelectrochemistry is presented. The spectroelectrochemistry experiment is based on the in-situ formation of a suitable substrate that enables the enhancement of the Raman signal of an analyte during the oxidation stage of a silver electrode. This phenomenon is known as electrochemical surface oxidation enhanced Raman scattering (EC-SOERS) and has proved to be useful in quantitative analysis using disposable screen printed electrodes. The successful combination of EC-SOERS with PARAFAC analysis allows the determination of uric acid in a relevant complex sample avoiding the use of standard addition method and without using a baseline correction, which simplifies the application of such methodology in routine analysis.
