چکیده انگلیسی
The contamination of surface and underground water by polyaromatic hydrocarbons (PAHs), such as phenanthrene, presents significant latent risk to humans and the ecosystem through the food chain. One of the sources of PAH pollution is the activities of the oil industry. A novel dendritic star-copolymer sensor system (Au|G3PPT-co-P3HT) for the determination of phenanthrene (PHE) in oil-polluted wastewater was prepared by in situ electrochemical co-polymerization of generation 3 poly(propylene thiophenoimine) (G3PPT) and poly(3-hexylthiophene) (P3TH) on a gold electrode. Electrochemical characterization and sensor application of the Au|G3PPT-co-P3HT electrode were performed by alternating current voltammetry (ACV), in a supporting electrolyte of 0.1Â M Bu4NClO4 in acetonitrile. The sensor parameters include a dynamic linear range (DLR) of application values of 2.78-37.65Â nM and a limit of detection (LOD) of 1.42Â nM (0.253Â ppb). The WHO guideline value for PAHs is 0.7Â ppb, which falls within the DLR of the dendrimeric sensor for PHE. The Au|G3PPT-co-P3HT was sensitive to PHE determination in oil-polluted wastewater.
