QUANTIFICATION OF DBPCONCENTRATIONS IN DPB-ETHANOL-WATER SOLUTION BY TERAHERTZ TIME-DOMAIN SPECTROSCOPY

摘要：

　　In order to investigate the plasticizersin liquor,the standard solution of ethanol and water with volume ratio of 53%are prepared and then a series of samples are accomplished by mixing a certain amount of DBP into standard solution.10 samples with different DBP concentrationsare studied by terahertz time-domain spectroscopy in range of 0.25 to 1.05THz.It is demonstrated that both the absorption coefficient and the refractive index decrease with the DBP concentrations and the DBP-ethanol-water solutions with different DBP concentration can be identified clearly by THz-TDS.The results of this paper lay a cornerstone for performing the noninvasive real-time measurement of plasticizers in liquor.
