Nitrogen 15 is an isotope of nitrogen that occurs in nature and contains two stable isotopes, nitrogen-14 and nitrogen-15. Among them, nitrogen-15 accounts for 0.365% of elemental nitrogen. Since the radioactive isotopes of nitrogen have short lifetimes, the longest-lived is nitrogen-13, but its half-life is only 9.965 minutes. period is only 9.965 minutes, it is less suitable for many applications. However, nitrogen-15, as a tracer atom for elemental nitrogen compounds, is widely used in agriculture, medicine and biochemistry.
One of the effective methods for the separation of nitrogen-15 is the chemical exchange method utilizing the nitric oxide to nitric acid system, which has been successfully applied in Germany This method has been successfully applied in Germany for the production of 250 compounds labeled with nitrogen-15. In addition, nitric oxide distillation is another method to obtain nitrogen-15. Nitrogen-15 has a wide range of applications, especially in agriculture. By applying nitrogen-15 labeled compounds to soil or fertilizer, the Nitrogen uptake, utilization and transformation process of plants can be tracked and studied. This is important for improving the nutrient utilization efficiency of crops and reducing the the amount of fertilizer used. In addition, N-15 can also be used to study nitrogen metabolism and protein synthesis in human body, which plays an important role in medical and biochemical research. and biochemical research.
In conclusion, as an isotope of nitrogen, N-15 plays an important role in agriculture, medicine and biochemistry. Through the use of nitrogen-15 labeled compounds, the the use of N-15-labeled compounds, the transformation and metabolic processes of nitrogen can be traced and investigated, which can provide an opportunity to realize sustainable agriculture and to deeply understand the behavior of nitrogen in organisms.The use of N-15-labeled compounds allows the tracking and study of nitrogen transformation and metabolism, providing a powerful tool for sustainable agriculture and in-depth understanding of nitrogen behavior in organisms.
