Interaction between 3d-transition metal ions (Mn2+, Fe2+, Fe3+, Co2+, Ni2+, Cu2+ and Zn2+) and the E(T)(30) dye, 2,6-diphenyl-4-(2,4,6-triphenyl 1-pyridino)phenolate in aqueous medium have been studied by distributing the dye between the aqueous and micellar phase formed by cationic surfactant cetyltrimethylammonium bromide(CTAB). Values of equilibrium constant K for the dye-metal ion interaction and the partition coefficient of the dye between the micellar and the aqueous phase have been determined. K values show a systematic correlation with ionic potential of metal ions.
通过将2,6-二苯基-4-(2,4,6-三苯基-1-吡啶基)酚盐（E(T)(30)染料）分布于由阳离子表面活性剂十六烷基三甲基溴化铵（CTAB）形成的水相和胶束相之间，研究了3d过渡金属离子（Mn2+、Fe2+、Fe3+、Co2+、Ni2+、Cu2+和Zn2+）与该染料在水介质中的相互作用。已测定了染料-金属离子相互作用的平衡常数K值以及染料在胶束相和水相之间的分配系数。K值与金属离子的离子势呈现出系统的相关性。
