Description

Sulfur K-edge X-ray Absorption Near Edge Structure spectroscopy was used to determine sulfur speciation in solid samples including bedrock, soils, and sediments. Linear combination fitting was used to quantify different sulfur forms including pyrite, elemental sulfur, sulfate, and organic sulfur.

Typical Equipment

  • synchrotron X-ray sources
  • XANES spectroscopy equipment
  • ATHENA software for data analysis

Output Measurements

  • sulfur speciation percentages
  • elemental sulfur content
  • pyrite content
  • organic sulfur content
