摘要
本文利用光学多道分析仪,着重研究了吖啶橙—银胶—吡啶体系;观察了吖啶橙荧光的两次瞬间增强的时间效应荧光谱;分析了吖啶橙与吡啶在银表面上共吸附竞争以及氯化钾在这一竞争中所起的作用。对于表面与分子间相互作用的这一规律作了初步探讨。
The dynamic process of Acridine Orong (AO) Ag sol Pyridine system was observed by using OMA. The coadsorption competition between AO and Pyridine on the surfaces of silver colloidal particles was researched on the time -effect fluorescent spectra, and the mechanism of KC1 in this coadsorption competition was discussed.
