| titleOfInvention | A method for rapid quantitative detection of organic phosphorus in soil |
| abstract | The invention relates to a method for rapid quantitative detection of organic phosphorus in soil. A soil sample is added to a mixed solution of 0.25M NaOH and 0.05M Na 2 EDTA, extracted by shaking in the dark, and then centrifuged, the supernatant is collected and filtered, and the supernatant is collected. Clear and freeze to obtain lyophilized powder; take 50 mg of lyophilized powder, dissolve it in 2 mL of paramagnetic ion solution, vortex and let stand to obtain a liquid 31 P NMR sample, which is detected by a Bruker 600MHz liquid nuclear magnetic resonance spectrometer. The chemical shift value of the P signal can determine the organic phosphorus form corresponding to the signal, and according to the relative ratio of the signal peak intensity, the relative abundance of a certain or a certain type of organic phosphorus can be determined to calculate its content. Compared with the common liquid 31 P NMR method, the invention shortens the detection time of the NMR experiment and improves the efficiency of quantitative analysis of soil organic phosphorus. |
