The formation of aggregate in reaction condition was confirmed by measuring the CMC value of SDS in aqueous medium and in the presence of propanol by conductivity measurements. The change in the size of aggregate, from DLS measurement, confirms the localization of reactant species towards the ...
SDS属于阴离子型表面活性剂,而CTAB属于阳离子型表面活性剂,两种溶液在较低浓度和较高浓度下的电导率均与溶液的浓度成线性关系,而在临界胶束浓度Cmc附近直线的斜率会发生明显的改变,根据两条直线的交点可求出此温度下SDS的Cmc。实验中通过测定一系列不同浓度的两种溶液的电导率,根据两条直线的交点得到临界胶束浓度Cmc...
The concentration of the solutions was deliberately selected so that their value was lower than the CMC value. The wetted surfaces in the experiment were: polytetrafluoroethylene (PTFE), polyethylene (PE), and aluminum (Al). The process of surfactant adsorption on a non-polar surface is largely...

1、大多指十二烷基硫酸钠。2、指抑郁自评量表。3、指猝死综合病症。4、指SDS系统设计规范。5、指学校疾病监测预警网络管理系统。6、指特别职务队。7、指音频软件保存格式。8、指结构化查询语言数据服务。9、指Students for a Democratic Society。
SDS的CMC的临界浓度,暂记为c。 。对PEC,4(~和 PEG20(~,c1值分别为5.68nnnol/L和7.03r~noUL。 这一实验事实说明,若要聚合物与表面活性荆分子 间具有强相互作用,则相应存在一个聚合物相对分 子质量阈值。因此,定义聚合物相对分子质量阈值 是表征聚合物与表面活性剂分子间存在强相互作 ...
