Quantification of Sulphate in Ambient Aerosols by FTIR Spectroscopy

Abstract:

Aerosols are important species in the Earths atmosphere and influence both air quality and climate in many important. In this article the relationship between IR absorption bands and SO₄^2- was discussed. Theν3 band of SO₄^2- in FTIR Spectra was studied when used as Na2SO4 . The results indicated that the peak positions of SO₄^2- were 984 cm-1 and 1133cm-1. And the relation between these peaks aera and the quality of SO₄^2- was well linear. And we give the value of α in band of 900-1300 cm-1. we measured all of the samples on the Ge and not a point, so the quantitive was not been affected by the nonuniform sample on Ge.
