Short summary
Ramped-temperature pyrolysis/oxidation (RPO) has been recently used to measure organic carbon properties in sediments, but the effects of pretreatment approaches on RPO results are unclear. We studied how acid rinsing and fumigation impact RPO analysis of organic carbon properties. Results show both methods and acid strength influence outcomes, with rinsing preserving natural states better. This research highlights the importance of method choice in accurate carbon analysis.
