By testing a series of solution ³¹P-NMR spectroscopy of model phosphorus compounds including inorganic phosphate,orthophosphate monoesters and diesters, and organic polyphosphate(determined in 1mol/L NaOH and 16.7% D2O), standard phosphorusspectra were obtained as references for solution ³¹P-NMR studies of sediment phosphorus. The results showed that the ³¹P-NMRsignals of phosphorus compounds interested in environmental studies generally fall between 6.5×10^-6 and -25×10^-6, includingorthophosphate at 6.412×10^-6, pyrophosphate at -4.353×10^-6, polyphosphate at -18.159×10^-6 to -20.246×10^-6 (middle group P) and-3.53×10^-6 to -4.40×10^-6 (terminal P), orthophosphate monoesters at 4.3540×10^-6 to 6.3652×10^-6, orthophosphate diesters at-0.107×10^-6 to 2.195×10^-6, and organic polyphosphate at -8.833×10^-6 to 9.499×10^-6 for the α-P.
