[Application and prospect of infrared spectroscopy in environmental science].

With the application of Fourier transform infrared spectrograph and the development of chemical metrology, Fourier transform infrared spectroscopy (FTIR) has become a kind of beneficial tool and means for analyzing samples. Especially with its strong identifying ability, exact determining results and fast response function, the application of FTIR method to environmental science has been popularized gradually. At present, people are launching applied study based on the specific property of FTIR in their corresponding field. Therefore, the present paper mainly introduced the current situation of study, progress and application of infrared spectroscopy in liquid, solid and gas environment state monitoring and qualitative analysis in the nearly past qualitative 10 years. In addition, the future development direction in environmental science is also discussed for its helpfulness in that field.
