Electrochemical sensors for emerging contaminants: diclofenac preconcentration and detection on paper-based electrodes

Abstract

A paper-based electrochemical sensor has been developed as a green tool for analysis of diclofenac. The electrochemical behaviour of diclofenac has been studied on carbon paper-based electrodes. A miniaturized device combining paper electrodes and reusable connections allows to perform descentralized analysis. The employment of a paper-based electrode allows simple on-site preconcentration of the analite improving the sensitivity of the methodology.
