The effect of anion microemulsion SDS/n-C4H9OH/n-C7H16H2O as a medium on Ferric-Thiocyanate complexes is studied at 20℃. The results show that the maximum absorption wave λmax balhochromic shift and the sensitivity is raised in comparison with water as a medium when the three kinds of microemulsions are used as the medium respectively such as O/W, W/O and transitional structure between them, hut the W/O microemulsion is the best medium. And the λmax ba-thochromic shift 20nm and the sensitivity is enhanced about one time when the W/O microemulsion containing 20% water is used.
