Soil-sulfur in Volcanic-ash derived soils was determined in soil extracts. The sulfur extracted was transformed into sulfate ions and organic matter destroyed by means of a 30% H2O2 solution. Sulfate ions were precipitated with a 15% BaCl2 solution and the precipitate then dissolved in (NH4)2 EDTA, and Barium determined by Atomic Absorption Spectrophotometry. Sulfur recovery was ascertained using an internal standard.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
