Photoacoustic determination of optical properties of aerosol particles collected on filters: development of a method taking into account substrate reflectivity

Abstract

The absorptivity of soot and methylene blue particles collected on Teflon filters is derived from photoacoustic measurements by least squares fitting a simple expression based on Beer’s law to the experimental data. Refinements of the expression take into account the diffuse reflection of light by the filter substrate, yielding a base 10 absorptivity at 600 nm for soot of 3.00 ± 0.37 m2/g. This value is in close agreement with the result of transmission measurements performed on the same samples (3.08 ± 0.05 m2/g).
