Abstract: Due to its advantages in improving our knowledge about the P fractions in environmental samples, the 31-P nuclear magnetic resonance (31P-NMR) technology has received extensive attention. This paper summarized the current studies on the characterization of P fractions in sediments by using this technology, and described the technical principles, sample preparation method and analytical procedures of this technol- ogy. The preparation procedures of environmental samples have a significant influence on the accuracy and precision of testing results, including determination of sample pretreatment, extraction time, sample to ex- traction ratio and concentration method. The specific application fields of this technology were also summa- rized in this paper. 31P-NMR technology has been applied in the field of Soil, Lake, Ocean, Wetland, and has made a number of achievements. Some future research focuses were expected in this paper in order to pro- vide theoretic support for the development and application as well as standardization of 31P-NMR technology in the future.
