摘要

For in-situ monitoring of polycyclic aromatic hydrocarbons (PAHs) in fresh water that flows from rivers into the oceans, a chemical sensor based on surface enhanced Raman spectroscopy (SERS) is well suited for a rapid identification and quantification of these substances. The laboratory set-up contains a microsystem light source at 488 nm suited for shifted excitation Raman difference spectroscopy (SERDS) and also a SERS substrate with a Ag nanoparticle ensemble with a plasmon resonance wavelength around 488 nm. SERS applying SERDS (SERS/SERDS) measurements of water samples containing 2 PAHs (pyrene and fluoranthene) showed Raman signals at 2 nmol/l and 1 nmol/l of concentration.
