应用微相吸附-光谱修正技术,研究了 Cu(II)、Ni(II)与酸性茜素蓝 B(AABB)在溴化十六烷基三甲铵(CTAB)胶束上的配位反应,分析了表面活性剂在配位反应中的增效机理,表征了二元和三元结合物的性质.结果表明,AABB-CTAB 作用符合 Langmuir 单分子层吸附,产物结合比为1:2.5,单体聚集形式为 AABB_2·CTAB_5,在20和40℃的结合常数分别为5.95×10~5和2.48×10~5;AABB-Cu-Ni 在 CTAB 胶束上配位反应的配位比分别为 AABB:Cu=1:1,AABB:Ni=1:25,三元产物聚集态为 Co_2·AABB_2·CTAB_(80)和 Ni_5·AABB_2·CTAB_(80).
The coordination reaction of Cu (II), Ni (II) and acid alizarin blue B (AABB) on cetyltrimethylammonium bromide (CTAB) micelles was studied by using microphase adsorption - The synergistic mechanism of the surfactant in coordination reaction was characterized and the properties of the binary and ternary conjugates were characterized.The results showed that the adsorption of AABB-CTAB conformed to the Langmuir monolayer adsorption, the product binding ratio was 1: 2.5, the monomer The binding constants of AABB-CTAB_5 were 5.95 × 10 ~ 5 and 2.48 × 10 ~ 5 at 20 and 40 ℃, respectively. The complexation ratios of AABB-Cu-Ni on CTAB micelles were AABB: Cu = 1: 1, AABB: Ni = 1: 25. The ternary product aggregates are Co_2 · AABB_2 · CTAB_ (80) and Ni_5 · AABB_2 · CTAB_ (80).
