Combining sequential extractions with bulk and micro X-ray spectroscopy to elucidate iron and phosphorus speciation in sediments of an iron-treated peat lake

The data of sequential phosphorus and iron extractions and synchrotron-based bulk and micro-focused X-ray absorption spectroscopy performed on peaty freshwater lake sediments presented in Münch et al. (2024) submitted to Royal Chemical Society - Environmental Science: Impacts & Processes. Details on the samples and methods can be found in the manuscript and the Electronic Supplementary Information.
