title: [Sensitizing effect of nonionic microemulsion on the derivative spectrophotometric determination of trace iron with sulfosalicylic acid].
abstract: 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.
