The influences of heterogeneous reaction on particle optical properties: a laboratory case of SO2 on hematite and hematite-NaCl mizture
The particle optical property variation for heterogeneous reaction of SO2 on hematite and hematite-NaCl mixture was investigated in a static reaction chamber at 298 K using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The increases of absorption and backward scattering coefficients are commonly higher in mixture with 50-70％ NaCl than pure hematite and other mixtures. For both pure hematite and mixture, under reactions of 1-10％ O2 concentrations, the absorption and backward scattering coefficients are in a higher increment than those of 20-30％ O2 concentrations. The absorption and backward scattering coefficients rise by commonly larger magnitudes at high SO2 concentration than low SO2 concentration, in a quicker approach to equilibrium.
