平衡和新奇 cationic 表面活化剂的动态表面紧张(DST ) , 3-(p-nonylphenoxy )-2-hydroxylpropyl trimethyl 铵溴化物,作为 RTAB 缩短了,被学习。象在它的 CMC 下面的 RTAB 答案的 DST 行为上的 NaCl, NaBr 和 NaI 那样的钠卤化物的效果详细被学习。由于优先的吸附,水和的效果并且外面腌,在一样的集中减少 DST 价值的能力在 NaI 的顺序 > NaBr > NaCl。归因于它的高表面活动,表面活化剂答案的 DST 的平衡时间对离子的力量感觉迟钝。
The equilibrium and dynamic surface tension (DST) of the novel cationic surfactant, 3-(p-nonylphenoxy)-2-hydroxylpropyl trimethyl ammonium bromide, abbreviated as RTAB, were studied. The effect of sodium halide such as NaCl, NaBr and NaI on the DST behavior of the RTAB solution below its CMC was studied in detail. Due to the preferential adsorption, the effect of hydration and salting out, the ability to reduce the DST values at the same concentration was in the order of NaI〉NaBr〉NaCl. Attributed to its high surface activity, the equilibrium time of the DST of the surfactant solution was insensitive to the ionic strength.
