摘要
利用太赫兹时域光谱结合化学计量学对塑化剂定量检测技术进行了研究。提出了一种利用太赫兹透射光谱测量超薄液体样品光学常数的新方法。利用该方法,以一种典型塑化剂--邻苯二甲酸二丁酯(DBP)为例,采用内径为200 μm的比色皿作为样品载体测量了不同浓度DBP-无水乙醇和DBP-乙醇-水溶液在太赫兹波段下的折射率和吸收系数。结果表明随着DBP含量的增加,DBP-乙醇溶液和DBP-乙醇-水溶液在太赫兹波段(0.2~1.1 THz)的光学参数随DBP浓度均呈有规律的变化。根据吸收系数面积、平均折射率相对DBP浓度变化曲线建立了未知溶液DBP含量的预测模型。该研究表明太赫兹时域光谱技术可能成为快速检测白酒等含乙醇饮料中塑化剂含量的新方法。
Abstract
The quantitative analysis for plasticizer based on terahertz (THz) time-domain spectroscopy and chemometrics is studied. A novel method for measuring the optical constants of thin liquid samples using THz transmission spectrum is presented. Taking a typical plasticizer, dibutyl phahalate (DBP) as an example, we use the method to determine the refractive index and absorption coefficient of DBP-ethanol and DBP-ethanol-water solutions with different DBP concentrations in THz regime, where a 200 μm path length cuvette is adopted as the sample holder. The results show that the optical constants of DBP-ethanol and DBP-ethanol-water solutions in the terahertz band (0.2-1.1 THz) change regularly corresponding to the DBP content. According to the average refractive index and absorption area the prediction model of DBP concentration in unknown solutions is constructed. The results demonstrate that the THz spectroscopy is a potential method for rapid identification of trace plasticizer in wine or other soft drinks.
