The Chinese Academy of Sciences has approved the establishment of an on-line monitoring instrument for total nitrogen total phosphorus in seawater

[China Instrument Network Instrument R&D] With the development of science and technology, many environmental problems have emerged, including seawater pollution. At present, the problem of eutrophication in closed sea areas has become quite serious, causing widespread concern. The contents of total nitrogen and total phosphorus in seawater can reflect the eutrophication of the marine environment to a certain extent. Therefore, monitoring total marine total phosphorus has become an indispensable part of marine environmental research.

Recently, the Ministry of Science and Technology announced the information on the 2017 special project for the "Special Protection of Marine Environment Security", led by the Xi'an Institute of Optics, Chinese Academy of Sciences, and the fish satellite researcher of the Key Laboratory of Spectral Imaging of the Chinese Academy of Sciences as the responsible person. The "Instrument Development and Industrialization" project was approved by the project.

The on-line monitoring sensor for total nitrogen and total phosphorus in spectrometry developed by this project will be a new type of spectroscopic instrument with complete independent intellectual property rights in China. After the project is successfully implemented, it will fill gaps in the field of total nitrogen total phosphorus monitoring instruments in seawater, and the technical indicators To achieve the international level of similar instrument products, can be widely used in marine ecological monitoring, disaster prevention and reduction and marine environment monitoring and other areas of operational monitoring, will be the major needs of our country's "transparent ocean engineering" construction, further exploration and application in the ocean The expansion of the field and the output of the results provide strong support.
