ResumoAbstract Sulfate is determined by titration with lead nitrate solution in aqueous acetone solutions buffered with nitric acid-pyridine, in presence of dithizone indicator. Sulfate is titrated directly or after separation from interfering ions and other materials on a column containing aluminum oxide and cation-exchange resin. The titration and separation are also applied to determination of sulfur in organic compounds after oxygen flask combustion. Details of the methods are fully discussed.
