Mackay, R A; Longo, F R

In this investigation both ionic (anionic and cationic) as well as non-ionic oil-in-water microemulsions have been used for various physico-chemical studies. The microemulsion systems employed are: sodium cetyl sulfate-heavy mineral oil-n-pentanol-water; cetyl trimethylammoniumbromide-hexadecane-n-pentanol-water and Brij-96-n-butanol-mineral oil-water. Porphyrin sensitized photoreductions of azo dyes have been extensively studied primarily in buffered Brij-96 microemulsion with limited studies in ionic systems. The experimental quantum yields for the reaction are normally in the range 0.10 to 0.27. The effect of nature of porphyrin, reducing reagent, reaction product(s), oxygen concentration and emulsion type on the experimental quantum yields are investigated. 8 tabs.
