运用太赫兹时域光谱技术定量分析柴油的含硫量
Quantitative determination of sulfur content in diesel using THz-TDS technology
摘要
Abstract
The frequency-dependent absorption characteristics of diesels with different sulfur content have been studied in the spectral range of 0.2-1.5 THz by the terahertz time-domain spectroscopy (THz-TDS).The absorption coefficient presented a regular change with the THz frequency and sulfur content,and the absorption coefficient increases with the frequency at the same concentration,vice versa.A nonlinear multivariate model was established and the sulfur content in diesel can be confirmed easily by means of the measured THz frequency-dependent absorption coefficient.The results made the quantitative analysis of sulfur content in diesel possible by THz-TDS technology and indicated the bright future in practical application.关键词
