Continuous measurement of sulfur in submicrometric aerosols. Report for Jun 1974--Jun 1975

Technical Report ·
OSTI ID:7311074
A method is described for measuring continuously the total sulfur in submicrometric aerosols suspended in air containing sulfur dioxide. The aero-colloid is passed through a tube coated internally with lead dioxide. The gaseous sulfur dioxide diffuses to the surface of the tube and reacts irreversibly to form lead sulfate. The aerosol is not significantly removed in the tube. The total sulfur in the aerosol is determined by a hydrogen-air flame photometric detector. A sulfur balance has been demonstrated for the sulfur dioxide-ozone olefine reaction system, which produces aerosols containing sulfur. (GRA)
