A Titanium(III) Chloride Based Approach for Accurate Measurement of Sulfate Oxygen Isotope composition

Key Points

• The aim is to improve the accuracy of measuring sulfate oxygen isotope composition to better understand its sources and transformation.
• Utilized titanium(III) chloride for sulfate analysis
• Addressed co-precipitation of nitrate to ensure accurate readings
• Assessed the measurement technique against standard isotopic methods.
• Significant reduction in measurement errors compared to traditional methods
• Achieved accurate δ18O-SO4 values that align with expected sources
• Demonstrated improved reliability in distinguishing source pathways of sulfate.
