Current methods for the quantification of different organic P compounds in environmental samples (e.g., soils, sediments) are based on extraction techniques and often associated with incomplete P recovery or sample changes. In this study, we present a protocol for the quantification of different organic and inorganic P species in soils using synchrotron-based X-ray absorption near-edge structure (XANES) spectroscopy at the P L2,3-edge. Its accuracy and precision was evaluated by analyzing 40 standard mixtures composed of seven different inorganic and organic P compounds (with a mean of R2 = 0.85). In addition, we quantified the P species of two soils and two agro-industrial byproducts using P L2,3-edge XANES spectroscopy and the results were compared with those obtained by P K-edge XANES or 31P NMR spectroscopy. Using the P L2,3-edge, we identified different organic P species, including those not identified by the common P K-edge XANES. However, there is a consistent underestimation of organic polyphosphates. Overall, the application of P L2,3-edge XANES provides a higher level of information than by P K-edge XANES, although the ubiquitous use of this novel methodology is still limited to samples with a phosphorus content above 3 mg g–1. 000887795 536__ $$0G:(DE-HGF)POF3-255$$a255 - Terrestrial Systems: From Observation to Prediction (POF3-255)$$cPOF3-255$$fPOF III$$x0 000887795 588__ $$aDataset connected to CrossRef 000887795 7001_ $$0P:(DE-HGF)0$$aSantana Amorim, Helen Carla$$b1 000887795 7001_ $$0P:(DE-Juel1)174576$$aKruse, Jens$$b2 000887795 7001_ $$0P:(DE-HGF)0$$aCriginski Cezar, Julio$$b3 000887795 7001_ $$0P:(DE-HGF)0$$aKlysubun, Wantana$$b4 000887795 7001_ $$00000-0001-5536-5777$$aPrietzel, Jörg$$b5 000887795 773__ $$0PERI:(DE-600)1465132-4$$a10.1021/acs.est.9b07018$$gVol. 54, no. 5, p. 2812 - 2820$$n5$$p2812 - 2820$$tEnvironmental science & technology$$v54$$x1520-5851$$y2020 000887795 8564_ $$uhttps://juser.fz-juelich.de/record/887795/files/Manuscript%20P%20L%20edge_Aceptedchanges.docx$$yPublished on 2020-02-18.
