Extraction of Elemental Sulfur from an Aqueous Suspension for Analysis by High-Performance Liquid Chromatography

摘要

A bioreactor is being developed that produces elemental sulfur suspended in aqueous bioreactor contents. The concentration of elemental sulfur must be measured explicitly in order to study the efficiency of the conversion of sulfide to elemental sulfur. Extracting the sample with ethanol gave erroneous results when sulfide was present in solution. The extraction of aqueous elemental sulfur into petroleum ether prior to colorimetric determination was tested.
