Soot Interference Mechanism On Measuring SO₂Concentration Using UV

Nowadays, with the rapid development of our country’s economy, environment isbecoming worse gradually.By using ultraviolet absorption of SO2concentration measurement smokeinterference mechanism of the main research content is as follows:Introducing the harmfulness of SO2and all kinds of testing method to determine theconcentration of sulfur dioxide detailed. After analyzing and comparing all kinds ofmethod to determine the concentration of sulfur dioxide, finally determined theultraviolet absorption method as the test method of the sulfur dioxide concentration in thesolution.Determining the ultraviolet absorption method to measure the concentration ofsulfur dioxide characteristic absorption wavelength of ultraviolet spectrum, this paperintroduces the principle of ultraviolet absorption method to detect sulfur dioxideconcentration, this paper introduces the testing method of particle concentration,ultimately determine the scattering method as a testing method to determine theconcentration of particulate matter, is studied using the Mie scattering theory of singlediameter particles and particle size particles of light scattering effect.Establishing a perfect data processing model, researching dissipation of particulate,non dissipative, average particle size, particle size, particle size distribution, scatteringlight accept range of ultraviolet absorption method measuring interference mechanism ofthe sulfur dioxide concentration of particulate matter in detail.By analysis of experimental data, which improved the precision of ultravioletabsorption method measuring the concentration of sulfur dioxide.Through the research on particulate matter interference, it can use mathematicalcalculation instead of dust removal equipment, so as to realize the low cost, highprecision, easy operation, and quick measurement of sulfur dioxide concentration.
