Study of the transport of small molecules in a microemulsion-based organogel is of great significance to broaden the research area of micellar enzymology and to promote its application in biosynthesis, bio-transformation and biosensor. The rate of the coordination reaction between divalent metal ions and murexide in a water-in-oil microemulsion was determined by spectrophotometric technique to study the transport of the metal ions entrapped in the organogel formed by cationic surfactant cetyltrimethylammonium bromide. The results indicated that transport of the metal ions from the organogel to the upper microemulsion was a rate-determining step for the coordination reaction. In order to confirm the conclusion, the effects of some factors, such as the molar ratio of water to the surfactant, the percentage of glycerol in the dispersed phase, on the transport were also studied and the same conclusion was obtained.

Key words: water-in-oil microemulsion, microemulsion2based organogel, coordination reaction, transport of small molecule, cationic surfactant
