本研究乃利用紫外可見光光譜儀, 測定三種染料分子 ( Disperse
Orange 1,Disperse Orange 3 和.alpha.-Naphthyl Red Hydrochloride)
分別在各種純溶劑與微乳液中的吸收光譜，並觀察其吸收區間與強度之變
化。實驗中，藉由改變微乳液中的共界面活性劑 (n-BuOH，Iso-BuOH，
Tert-BuOH和n-PeOH)，與油相的種類 (Benzene，Toluene，Cyclohexane)
及在微乳液中之重量百分比，來探討染料在光譜中的變化。並判斷染料在
微乳液中的溶化位置，影響染料溶解度之因素。尋找出如何選擇最適宜之
共界面活性劑及油相，使染料在微乳液中達到最大的溶解效應。並發現
Disperse Orange 1 在 n-BuOH， SDS/水/Toluene 系統中會有最大溶解
度 (0.0942 g/L)。.alpha.-Naphthyl Red Hydrochloride 在系統 n-
BuOH, SDS/水/Benzene 中溶解度最大 (0.0529 g/L) 。 而 Disperse
Orange 3 在系統 n-BuOH, SDS/水/Toluene 或 Benzene 中有最大的溶
解度 (0.0494 g/L, 0.0491 g/L)。

The study is to determine the solubility of three kinds of dyes
in pure solvents and various microemulsions using the UV-VIS
spectrophotometer. In experiment, we change the type and the
amount of cosurfactants such as n-BuOH, iso-BuOH, tert-BuOH, n-
PeOH , and the type and the amount of oil phases such as
benzene, toluene, cyclohexane, and then, measure their
absorption maximum position and their optical density, owing to
optical density is proportional to its concentration. We can
easily to determine the solubility of dyes in various
microemulsions. The shift in absorption maximum in various
microemulsions will give us estimation of the approximate
location in microemulsions. The maximum solubility of Disperse
Orange 1 in n-BuOH/SDS/ Water/Toluene solvent system is 0.0942
g/L. The maximum solubility of Disperse Orange 3 in n-BuOH/SDS/
Water/Toluene, Benzene solvent system is 0.0494 g/L, 0.0491 g/
L. The maximum solubility of .alpha.-Naphthyl Red Hydrochloride
in n-BuOH/SDS/ Water/Benzene solvent system is 0.0529 g/L.
