| Abstract: |
| Phytic acid modified Au (IP6@Au) nanoparticles with high surface enhanced Raman scattering (SERS) activity as well as hydrophobicity were synthesized.Based on IP6@Au and the molecular fingerprint information,we developed a SERS-based method for simultaneous detection of four polycyclic aromatic hydrocarbon species in river water by using a portable Raman system.The limit of detection for anthracene,fluoranthene,pyrene and benzopyrene were 100,100,10 and 1 μg/L,respectively. |
| Key words: surface enhanced Raman scattering IP6@Au anthracene fluoranthene benzopyrene pyrene simultaneous detection |
