An electrochemical platform based on CuO/N-rGO nanocomposite and IL for the determination of ۲-aminophenol

In last decade, the protection of environment from the pollution is global concern. [۱]. ۲-amino phenols are aromatic compounds contains amino and hydroxyl group adjacent to each other on benzene ring, they are good reducing agents, chemically reactive and amphoteric in nature. ۲-amino phenols are possessing toxic effects because of its easy penetrating property into the skin, membranes of plants and animals causes genotoxic, mutagenic and hepatotoxic effects. In the recent years, nanomaterials based electrochemical sensors have found a lot of utilizations due to their unique properties. The unit features such as larger ratio of the surface to volume involve in higher sensitivity and new sensing features of nanomaterials. Furtheremore, ionic liquids (ILs) are widely employed in electroanalysis, particularly for designing sensors based on the electrode modifications due to their unique features, including lower volatility and higher ionic conductivity [۲]. In this work, we reported the electrochemical sensing of ۲-aminophenol by using a carbon paste electrode (CPE) modified with CuO/N-doped reduced graphene oxide (CuO/N-rGO) nano-composite and IL. The prepared sensor has outstanding performance in the determination of ۲-aminophenol with higher sensitivity, wider linear ranges, and a lower limit (۰.۰۳ μM) of detection.
