| Abstract: | Improvements are described to Flynn's procedure for the extraction of sulphate with Aliquat-336 and its subsequent determination as sulphuric acid. A single-point photometric measurement with sodium 2,4-dinitrophenate is applied to the determination of sulphate (ca. 10 mg kg?1) in soils, and also in sulphur in organic compounds after oxygen flask combustion. |
