微乳液是由表面活性剂、助表面活性剂、油与水等组分在适当比例下组成的无色、透明、低粘度的热力学稳定体系,从结构上可分为O/W型、W/O型和油、水双连续型三类。离子型表面活性剂组成的离子型微乳液的结构可用电导法确定。与胶束体系比较,微乳液具有超低界面张力(10~(-3)～10~(-4)dyne·cm~(-1))和很高的增溶能力,其增溶量可高达60～70%。Ezio Pelizzetti曾指出,作为胶体缔合结构之一,微乳液应具有增敏作用。我们曾研究了W/O阴离子型微乳液介质对硫氰酸铁(Ⅲ)体系的增敏作用。本文则研究了以O/W阴离子型微乳液为介质,
Microemulsion is a colorless, transparent and low viscosity thermodynamically stable system composed of surfactant, cosurfactant, oil and water in suitable proportion, which can be divided into O / W type and W / O-type and oil, water double continuous three categories. The ionic surfactant composed of ionic microemulsion structure can be determined by conductivity method. Compared with the micellar system, the microemulsion has ultra-low interfacial tension (10 -3 to 10 -4 dyne · cm -1) and high solubilization capacity, and its solubilization capacity can reach as high as 60 ~ 70%. Ezio Pelizzetti has pointed out that as a colloidal association structure, microemulsion should have sensitization. We have investigated the sensitizing effect of W / O anionic microemulsion media to iron (III) thiocyanate systems. This article is to study the O / W anionic microemulsion medium,
