A method is described for the continuous measurement of total sulfur in submicrometric aerosols suspended in air containing sulfur dioxide. The aerocolloid 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-olefin reaction system, which produces aerosols containing sulfur. (Copyright (c) Pergamon Press Ltd. 1978.)
