溴代十六烷基吡啶微乳液体系的电导行为研究

Conductivity Behavior of Microemulsion System of Hexadecylpyridine Bromide

研究了pH值、温度、盐及其浓度变化对溴代十六烷基吡啶/正丁醇/苯/水微乳液体系电导率变化趋势的影响。结论表明,pH值对体系的电导率没有明显影响,50℃以上时,微乳液体系在碱性条件下比在酸性条件下稳定。当体系加入不同盐时,电导率随温度升高、盐浓度的增大而增大;同样条件下,硫酸钠体系的电导率要比氯化钠体系高。

The influences of pH value, temperature, hexadecylpyridine bromide / n-butanol / benzene / water salt and its concentration on the conductivity behavior of microemulsion system have been studied. The results show that pH value has less effect on the conductivity of microemulsion. When temperature above 50℃, the alkaline system is more stable than the acidic system. The conductivity of the microemulsion increases with the salt concentration and temperature as the different salt was added. The conductivity of the Na2SO4 system is higher than NaCl system at the same temperature and salt concentration.
