Sulfuric acid aerosol and total sulfates can be determined by formation of permidylammonium sulfate and subsequent thermal decomposition to form quantitatively sulfur dioxide. The SO/sub 2/ may be determined by the West-Gaeke procedure or by means of a flame photometric sulfur monitor. Airborne particulate samples are analyzed by isolating the H/sub 2/SO/sub 4/ by microdiffusion, and total sulfate is determined by aqueous extraction of the particulate samples. A working range of 1-50 ..mu..g of sulfate can be handled conveniently. The determination (excluding microdiffusion) requires only a few minutes.
