Lead X-ray absorption near edge spectroscopy (XANES) linear combination fit modelling

Dataset is Lead speciation analysis by X-ray absorption spectroscopy and linear combination fitting modelling with known lead standards. Samples were from a potted incubation experiment where lead paint chip contaminated soil was amended with 3 different sources of phosphorus: triple super phosphate, potassium phosphate, and bone meal. Phosphorus was amended at 3 different phosphorus rates. Soil was allowed to incubate at room conditions for 159 days with rewatering to maintain moisture. Subsamples were measured from each incubation pot after 30 and 159 days (T1 and T2). Paint chip contamination source contained a mixture of anglesite (lead sulfate), massicot (lead oxide) and cerussite (lead carbonate). Lead species in soil contained a mixture of lead adsorbed to iron oxides, lead oxide, and lead sulfate. No lead phosphate species were identified in any samples indicating that methods used in this study did not transform soil lead to desired form for remediation of lead. This dataset is associated with the following publication: Madsen, J., Z. Dascalos, K. Ramsey, F. Mayer, C. Wong, Z. Raposo, R. Hunter, M. Reinhart, A. Carlson, A. Catlin, T. Mihelic, Z. Pfahler, A.
