项目摘要

In recent years, there has been an increasing interest in developing the numerous analytical applications of surfactant micellar systems that have the ability to concentrate and to compartmentalize within their distinct microstructured regions compounds of different nature. For chemiluminescence (CL) measurements, we have used a reversed micellar system as a medium, which provide a unique and versatile reaction field. The center of a reversed micellar core is filled with water surrounded by surfactant polar heads. We have pointed out that a surfactant-water interface of the reverse micelle could play a significant role in the CL reaction processes with metal complexes: At the reversed micellar interface, metal ions are produced transiently from the dissociation of metal complexes and then immediately catalyze the CL reaction in the aqueous phase.In order to enhance and/or improve the analytical performance of this method based on the reversed micellar-mediated CL reaction, there has be … More en a great need to understand the reaction specificity of metal complexes at the reversed micellar interface and further the unique function of reverse micelles as microreactors for analytical use. Thus, this research focused on the following : (1) Solvatochromic shifts of absorption spectra of (5, 10, 15, 20-tetraphenylporphyrinato)zinc(II) and 1, 4, 8, 11-tetramethyl-1, 4, 8, 11-tetraaza-cyclotetradecanenickel(II) dispersed as a probe in reversed micellar solutions and reversed micellar effects on the coordination equilibria of anions and water to the metal complexes. (2) Acid-dissociation of the zinc(II) complex with 5, 10, 15, 20-tetraphenyl-porphyine and formation of tris iron(II) complex with 2, 2'-bipyridine at the reversed micellar interface, investigated by using a stopped-flow spectrophotometer. (3) Reversed micellar mediated luminol CL reactions with the iron(III) complex of 8-quinolinol and the oxovanadium(IV) complex of acetylacetone. (4) Development of new flow-injection methods based on solvent extraction coupled on-line to the reversed micellar-mediated CL detection system for trace-level determinations of iron(II, III), iodide and/or iodine and atropine.
