中文摘要:

在 n-C5H11OH/H2O=50/50 的重量比率,当钠 dodecyl 硫酸盐(SDS ) 的全部的内容是不到 6.0% 时, SDS/n-C5H11OH/H2O 的第三的混合在二不能混合的微乳液共存了。在二个阶段之间的 gatifloxacin (GTFX ) 的分发和转移被学习用紫外力并且电气化学交流阻抗系列。结果证明 GTFX 从上面的阶段( W/O )转了到更低的阶段( O/W 或 bicontinuous 微乳液),吗但是 SDS 的小数量在 1.0 畲獧的全部的 GTFX 集中随全部的 SDS 内容的增加相应地从更低的阶段转了到上面的阶段?

英文摘要:

At a weight ratio of n-C5H11OH/H2O=50/50, when the total content of sodium dodecyl sulfate (SDS) was less than 6.0%, the ternary mixture of SDS/n-C5H11OH/H2O coexisted in two immiscible microemulsions. The distribution and transfer of gatifloxacin (GTFX) between the two phases were studied using UV-Vis and electrochemistry AC impedance spectra. The results show that GTFX transferred from the upper phase (W/O) to the lower phase (O/W or bicontinuous microemulsion), but a small amount of SDS transferred from the lower phase to the upper phase correspondingly with the increase of the total SDS content at a total GTFX concentration of 1.0×10^-5 mol/L. The addition of GTFX did not change the structures of the two different phases fundamentally, but resulted in the transfer and redistribution of GTFX and SDS, so the electric properties of the system were changed correspondingly.
