摘要
本文作者制备了硫化镉(CdS)的十二烷基磺酸钠(SDS)胶体(CdS/SDS),测定了其UV-Vis吸收光谱和荧光发射光谱,用自旋捕捉-ESR技术研究了一些无机盐、有机盐和几种有机物分别在 CdS/SDS胶体系中的光反应产生的活泼自由基.
Colloidal cadmium sulfide (CdS) stabilized with sodium dodecyl sulfidate (SDS) was prepared. Its UV-Vis absorption and fluorescence spectra were measured. The free readicals appearing during illumination of colloidal cadmium sulfide system containing inorganic or organic salts or some other organic substances were studied by using the technique of spin trapping-ESR. The photoreactions were discussed from the points of thermodynamics.
