摘要
本文对超高交联树脂的太赫兹光谱进行了研究.对树脂本体的测量表明在1THz附近其存在一个宽化的弱吸收峰。当树脂吸附了弱酸性的苯酚后,树脂微孔与苯酚分子发生相互作用,使树脂的吸收峰的强度发生明显的变化,这个结果说明太赫兹光谱可以用来研究表面吸附现象,这对物理化学和环境化学有重要的意义。
A hypercrosslinked adsorption resin is researched by Terahertz time-domain spectroscopy(THz-TDS). It is indicated that there is a broadened but small absorption peak of resin itself around 1THz. The intensity of this peak obviously changes when resin adsorbs phenol with weak acidity, for there is some interaction between phenol and micropore. This result shows that the terahertz spectrum can be used in the research of surface adsorption, which provides great importance for physical chemistry and environmental chemistry.
