摘要: 研究了青霉素钾对十六烷基三甲基溴化铵(CTAB)的cmc、CTAB胶束聚集数和扩散系数的影响.研究结果表明,青霉素钾(PenK)的加入使得CTAB胶束的第一cmc、第二cmc上升;CTAB球形胶束的聚集数下降,扩散系数增加;CTAB棒状胶束的聚集数增加,扩散系数降低.

关键词: CTAB, 聚集数, cmc, 扩散系数, 青霉素钾

Abstract: The effects of penicillin potassium salt on the cmc,the aggregation numbers and the diffusion coefficients of CTAB micelles have been studied.Addition of penicillin potassium salt increases the first cmc and the second cmc,decreases the aggregation numbers of micelles and increases the diffusion coefficient when CTAB concentration is between the first cmc and the second cmc. However,when CTAB concentration is higher than the second cmc,addition of penicillin potassium salt increases the aggregation numbers but decreases the diffusion coefficient.
