The sensitizing effect of O/W microemulsion of Triton X-100/n-C5H11OH/n-C9H20/H2O as a medium on the derivative spectrophotometry of Fe-Sal was studied. The results show that the sensitivity of determination in O/W microemulsion was higher than that in micelle. The reagent Sal has higher distribution coefficient KD and constant K in microemulsion than in the micelle system and lower binding in O/W microemulsion than in the micelle system. This results also illustrate that O/W microemulsion has more solubilization for Sal than micelle does, so that O/W microemulsion has more sensitizing reaction than micelle does.
研究了以Triton X - 100/正戊醇/正壬烷/水的O/W微乳液为介质对铁 - 水杨酸衍生物分光光度法的增敏作用。结果表明，在O/W微乳液中测定的灵敏度高于在胶束中的灵敏度。试剂水杨酸在微乳液中的分配系数KD和常数K高于胶束体系，且在O/W微乳液中的结合率低于胶束体系。该结果还表明，O/W微乳液对水杨酸的增溶作用比胶束更强，因此O/W微乳液比胶束具有更强的增敏反应。
