Raman Spectroscopy Of Carbonaceous Particles Of Environmental Interest
JOURNAL OF RAMAN SPECTROSCOPY(2015)
摘要
Carbonaceous particles of environmental origin are practically insoluble, which constitutes an obstacle to many chemical physical characterization techniques. Micro-Raman spectroscopy overcomes the sample preparation step and can be applied on the as-received sample and even in situ, with nowadays commercially available portable Raman equipment. Multivariate statistical analysis of Raman data recorded on a variety of carbonaceous particles of different origin, through a molecular interpretation of the signal, shows that the use of Raman spectroscopy with several excitation sources can provide a useful tool for assisting the characterization of various forms of environmental carbon matter.
