Pretreatment method for nitrogen and oxygen isotope measurement with chemical conversion method and measurement method |
| abstract |
A pretreatment method for nitrogen and oxygen isotope measurement with a chemical conversion method and a measurement method, relating to the technical field of environmental protection and monitoring. The pretreatment method comprises the following step: performing low-temperature treatment on a sodium azide-acetic acid buffer solution at a temperature lower than or equal to 15°C. According to the method, low-temperature treatment is performed on a sodium azide-acetic acid buffer solution at a temperature lower than or equal to 15°C, so that the interference of the sodium azide-acetic acid buffer solution on N2O obtained from the reaction of a nitrate in a sample during test can be greatly reduced, and the precision of a test result is improved. |
