| 摘 要： | 用半导体精密量热计测得25±0.01℃时溴化银从DMF-H2O溶液中吸附噻碳菁染料(Ⅰ)的吸附热。发现由于溶液中染料聚集状态的不同导致吸附热明显不同,但吸附于溴化银表面的染料的聚集态则基本相同。

| Abstract: | The states of aggregation of 3,3’-di-(y-sulfoporopyl)-9-ethyl-4,5,4’,5’-dibenzo-thiacarbo-cyanine (I) in DMF-H2O (15%DMF,v/v) solutions as well as on AgBr surface were studied by absorption and reflection spectra at room temperature.Adsorption heats of dye I on AgBr are obtioned calorimetrically from two solution of dye I in different aggregation states at 25±0.0001℃.The ΔH values (in kJ/mol dye) obtained are quite different.However,the reflection spectra and the isotherms at 25℃ showed almost the same adsorption state of dye I on AgBr.These results may give some information on the adsorption of dye I on AgBr surface. |
