Abstract:
The coordination reactions of Cu(Ⅱ) and Ni(Ⅱ) with acid alizarine blue B (AABB) in the presence of cetyltrimethylammonium bromide (CTAB) micelle were investigated using the microsurface adsorptionspectral correction technique (MSASC). The aggregation of AABB on CTAB followed the Langmuir isothermal adsorption law. The enrichment of AABB on CTAB sensitized the complexation between Cu(Ⅱ) or Ni(Ⅱ)and AABB. The binding ratio of AABB to CTAB was 1:2.5, and monomeric aggregate, AABB2CTAB5, was formed with an adsorption constant of 5.95×105 at 20 ℃ or 2.48×105 at 40 ℃. In the ternary complexation, the ratio of AABB:Cu and AABB:Ni were 1:1 and 1:2.5, respectively. Two types of aggregates, Cu2.AABB2·CTAB80 and Ni5.AABB2.CTAB80, were formed.

摘要:
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AABB2.CTAB5,在20和40 ℃的结合常数分别为5.95×105和2.48×105;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=1:2.5,三
