项目摘要

The UV-visible internal reflection spectrometer with variable angle of incidence was manufactured. Some features of the spectrometer were investigated. Because a halogen lamp was used as the light source and the optics contained optical fibers, the angle of incidence showed a divergence of <plus-minus>1.5゚. This divergence gave no efects to the internal reflection spectroscopic measurements except for in the range of the angle of incidence near the critical angle. By using a dye solution which is not adsorbed by glass, the relationship was tested between the reflection absorbance and the optical path of the internal reflection spectroscopy (the effective thickness) which was variable by changing the angle of incidence. The result indicated that the reflection absorbance was proportional to the effective thickness and that the proportional constant was equal to the molar absorption coefficient of the dye solution. This fact shows that the spectrometer made has the expected features. Adsorption of a water-solble porphrin onto glass was investigated in the presence of a cationic surfactant with the spectrometer. The interfnal reflection spectroscopic observation indicated readily as well as in situ that the water-soluble porphrin was adsorbed by the glass-solurion interface. The pH dependence of the adsorption showed that the species adsorbed was the deprotonated form of the porphrin and that electric charges on the glass surface greatly effected the adsorption behavior of the porphrin for the high pH solution. It has been suggested the internal reflection spectrometer made here is useful for the in situ observation of the solid-liquid interface. In addition, the internal reflection spectroscopy has been applied to the study of the liquid-liquid interfac
研制了可变入射角的紫外-可见内反射光谱仪。研究了光谱仪的一些特性。因为卤素灯被用作光源并且光学器件包含光纤,所以入射角显示出1.5 °的发散<plus-minus>。这种发散除了在临界角附近的入射角范围内对内反射光谱测量没有影响。通过使用不被玻璃吸附的染料溶液,测试了反射吸光度与通过改变入射角而变化的内反射光谱的光程(有效厚度)之间的关系。结果表明,反射吸光度与有效厚度成正比,正比常数等于染料溶液的摩尔吸光系数。这一事实表明,所研制的光谱仪具有预期的特点。本文研究了在阳离子表面活性剂存在下,水溶性卟啉在玻璃上的吸附。内反射光谱的观察表明,水溶性卟啉被吸附在玻璃-溶液离子界面上。吸附的pH依赖性表明,吸附物种是去质子化形式的卟啉和玻璃表面上的电荷大大影响卟啉的吸附行为的高pH值的溶液。提出了用自制的内反射光谱仪对固液界面进行原位观测的设想。此外,内反射光谱还被应用于液-液界面的研究,
