摘要: 利用UV-Vis吸收光谱仪和光化学反应器,研究了菁染料和份菁染料的光降解动力学.研究结果表明,染料在乙腈溶液中的光褪色反应遵循假一级或零级动力学衰减.与相应的份菁染料相比,携带正电荷的菁染料具有相对较好的光稳定性.

关键词: 菁染料, 光稳定性, 份菁染料, 光降解

Abstract: The photodegradation kinetics of cyanine dyes and merocyanine dyes were studied by UV-Vis absorption spectroscopy. The results show that the rate of the photofading reactions of the dyes follows quasi-first-order or zero-order kinetics in acetonitrile. Those cyanine dyes holding a positive charge have relative good photostability comparing with merocyanines.

Key words: cyanine dyes, photostability, merocyanine dyes, photodegradation
