Spectroscopic Methods of Analysis for Polycyclic Aromatic Hydrocarbons in the Aqueous Environment

摘要: I. INTRODUCTION A number of new techniques based on spectroscopic principles are being developed for the analysis PAH as possible alternatives to chromatographic methods discussed in our earlier review.1 The following sections address themselves one or both two broad developmental goals. first is need analytical procedures which (1) selective several PAH, (2) capable detecting subnanogram amounts (3) able provide results a real-time basis, (4) portable, inexpensive, and easy enough be automated run by technicians, all without preseparations. Synchronous spectroscopy, room temperature phosphorimetry, matrix isolation spectroscopy can satisfy these requirements. second important goal developing instrumentation devise detectors obtaining more information especially from HPLC less urgently GC instruments. At present, mass spectr...
