文摘The individual particles collected from a power station were analyzed by time of flight secondary ion mass spectrometry (TOF SIMS). The result indicates the presence of the polycyclic aromatic hydrocarbon (PAHs) as well as the oxygenated one. They might be derived from the incomplete combustion of coals. SIMS has proved to be a rapid method for the qualitative analysis of PAHs and OPAHs absorbed on the aerosol particles. New perspectives for better understanding the SIMS spectra obtained from complex mixture such as environmental samples have been opened.
