Read： 401 Time：5months ago Source：Ease of the world

Nitrile, as an important raw material for organic synthesis, plays an important role in industrial production, scientific research and pharmaceutical manufacturing. Corresponding to its importance, butyronitrile may cause serious harm to the human body and the environment at a certain concentration. Therefore, the development of efficient and accurate nitrile detection methods and analysis techniques is of great significance to ensure production safety, environmental protection and people's health.

At present, the detection methods of nitrile mainly include traditional gas chromatography, liquid chromatography, spectroscopy and so on, as well as the methods based on biotechnology that have gradually emerged in recent years. Gas chromatography is widely used in the analysis of nitrile because of its high resolution and high sensitivity. The quantitative and qualitative analysis of butyronitrile can be achieved by gas chromatography combined with mass spectrometry, with high accuracy and reliability. The method of liquid chromatography is suitable for the detection of butyronitrile in liquid environment, and its operation is simple, fast and efficient. The spectral law can be used to detect butyronitrile by means of absorption spectrum and fluorescence spectrum, which has the characteristics of fast and non-destructive.

In addition to the traditional physical and chemical methods, in recent years, the detection method of nitrile based on biotechnology has gradually attracted attention. For example, the use of biosensors and enzyme-specific reactions can achieve high sensitivity detection of butyronitrile, and has the advantages of simple operation and rapid response. The introduction of biotechnology not only improves the sensitivity and specificity of detection methods, but also provides new ways and possibilities for real-time monitoring and on-site rapid detection.

With the development of social economy and the improvement of people's living standards, more and more attention has been paid to environmental quality and food safety. Nitrile (NBR) is a kind of harmful substances that may exist in industrial wastewater, air pollutants and food. Its detection and analysis is of great significance for environmental monitoring and food safety.

In terms of environmental monitoring, the sources of nitrile are diverse, including industrial wastewater, atmospheric emissions, and pesticide residues. Therefore, it is essential to establish a comprehensive and accurate NBR detection network. The use of advanced detection technology can achieve rapid monitoring and accurate analysis of the concentration of nitrile in the environment, providing scientific basis and technical support for environmental protection.

On the other hand, residues of butyronitrile in foods are also of concern. Unqualified food may cause serious harm to human health, so the detection and analysis of nitrile in food is particularly important. Through the establishment of efficient and reliable detection methods, potential food safety hazards can be found and eliminated in time to ensure public health and food safety.

The detection method and analysis technology of nitrile have important application value in industrial production, environmental monitoring and food safety. With the continuous progress and innovation of science and technology, it is believed that more and more efficient nitrile detection methods and analysis technologies will emerge in the future, making greater contributions to the protection of people's health and environmental protection.
