| 摘 要： | 通过向十二烷基硫酸钠(SDS)/正丁醇/二甲苯/水溶液(FeSO4)组成的微乳体系中加入不同浓度NaCl溶液,测量体系在不同温度下的电导率和pH值,讨论了盐效应和温度对微乳体系的影响.结果表明:体系的电导率随着盐浓度增加和温度升高而变大,pH值随温度的升高而减小.向FeSO4微乳液体系加入NaCl溶液后发现:当温度低于20℃时,加入0.01 mol*L -1NaCl溶液,体系的电导率即高于原微乳液体系的电导率;当温度在20-35℃之间时,氯化钠浓度需达到0.06 mol*L -1,体系的电导率才高于原体系的电导率;温度高于35℃时,只有氯化钠浓度超过0.08 mol*L -1,体系的电导率才会高于原体系的电导率.
