| 摘 要： | 本文用计时电位法及电位滴定研究了十六种不同染料与溴化银之间的相互作用,进一步证明了具有离域π-电子的菁染料才能与卤化银形成络合物的论点。从得到的平衡常数K表明,固体表面上的卤化银-染料与溶液中银离子-染料具有相同键性质,都是银离子与染料离域π-电子作用的结果。

| Abstract: | In this paper,The nature of interaction between 16 dyes and silver bromide were investigated by chronopotentiometric and potential titration methods.It supported the postulation that only cyanine dyes with delocalized electrons can form complex with silver bromide.The obtained equilibrium constant K suggested that both interaction between silver bromide and dye on solid surface and silver ion and dye in solution have the same nature which was caused by interaction of silver ion and delocalized π-electrons of cyanine dyes. |

| Keywords: | chronopotentiometry potential titration transition time delocalized π-electron complex |
