| 摘 要： | 利用化学还原的方法制备银溶胶，通过在吸附了活性艳红的高岭土基体上沉积银，获得了活性艳红在高岭土上的表面增强拉曼光谱，探讨了活性艳红在高岭土上的吸附机理．结果表明，活性艳红和银溶胶均以范德华力和静电引力直接吸附于高岭土上。且银溶胶对活性艳红在高岭土上的拉曼信号有显著的增强效应。

| Abstract: | Through the chemical reduction method we prepare the silver colloid.With with the help of the deposit silver on Kaolinite matrix which has absorbed reactive red,we obtain the surface enhanced raman scattering of reactive red on Kaolinite.This paper elaborates on the absorption me chanism of reactive red on Kaolinite.The results indicate that both the reactive red and the silver colloid are directly absorbed on Kaolinite by Van der force and electrostatic force.The deposited silver colloid on Kaolinite has an intense enhanced effect of raman scattering of the absorbent. |
