Spectroscopic Approaches for Phosphorus Speciation in Soils and Other Environmental Systems.

The article presents a study on the spectroscopic approaches for phosphorus speciation in soils and other environmental systems in the U.S. It cites the four spectroscopic techniques used in the analyses of the most common chemical species of phosphorus (P) reported for soils, sediments and waste materials including X-ray absorption near-edge structure (XANES), nuclear magnetic resonance (NMR) and Fourier transform infrared spectroscopy (FTIR). It notes the inorganic and organic P species revealed by the XANES and NMR in intact environmental matrices and the adsorbed P species provided by FTIR and Raman techniques.
