Extraction of iron and manganese from sediments using 0.5 N HCl with hydroxylamine hydrochloride in anaerobic conditions, followed by ICP-AES analysis. This method targets metals associated with reducible phases in sediments.
Synthesized from method descriptions across 3 papers using this protocol.
Steps below were extracted from the most recent peer-reviewed implementation of this protocol in the corpus — Reactive iron, not fungal community, drives organic carbon oxidation potential in floodplain soils (2023), Soil Biology and Biochemistry. Implementations in other papers (listed below) may differ.
