Quantitative analysis on toluene contents in hexane solution using terahertz time domain spectroscopy

摘要

The effective dielectric permittivity of a mixed organic solution was measured by terahertz time domain spectroscopy (THz-TDS). The experimentally obtained effective dielectric permittivity of hexane/toluene mixed organic solution was well fitted by the effective medium approximation (EMA) model. Discrepancy between experimental results and calculations from 0.5 to 3.0 THz is estimated to be 0.28%.
