Electrochemical Detection Of Protracted Environmental Pollutants PAHs

Polycyclic aromatic hydrocarbons（PAHs） has been one of organic pollutants that allcountries in the world pay attation to. The accumulation of polycyclic aromatic hydrocarbonshas become a serious threat to human health. The detection method of polycyclic aromatichydrocarbons was so complicated, and can not guarantee real-time detection. There is anurgent need to develop a rapid and sensitive detecting method of polycyclic aromatichydrocarbons.At this treatise we suggested a method that the electrochemical probe can be used todetect the polycyclic aromatic hydrocarbon. The detail as follow:1Electrochemical behavior of anthraquinone sulfonate has been researched. It wasmondenfied on the surface of glass carbom electrode to detect Philippines.2Synthesis of sulfur viola and graphene has been made. The glass carbon electrode hasbeen modifide by Nafion/sulfur viola and grapheme. The electrode was used to detect thetotal amount of tricylic polycyclic aromatic hydrocarbons--anthracene and phenanthrene.3Alizarin Red (AQS) was modified mesoporous materials SBA-15as a probe. Theelecode was modifide by AQS-SBA-15to detact the contect of anthracene.4Benzanthraquinone7,12-dione was modifide on the electrode surface by theelectro-polymerization of pyrrole. Based on this, a method of detect the amount of benzoanthracene has been built.
