中文摘要 | 有關月桂基硫酸鈉在食鹽中之界面特性,包括表面張力、導電度、界面電位及粒徑變化,本實驗利用表面張力法,發現月桂基硫酸鈉的CMC值在7×10³M。由電導度法求出CMC值為0.2%。而藉由光子相關函數光譜學量測其粒徑、界面電位,由實驗結果顯示在月桂基硫酸鈉之界面電位隨濃度變化中有明顯之折點。此明顯之折點乃為量測界面活性劑CMC值新方法之探討所在。 |
英文摘要 | In this work we have studied the aqueous solution of anionic surfactant, sodium laury sulfate, its CMC value is 0.2% (in room temperature) which is determined by the method of conductance measuring with different concentrations of sodium lauryl sulfate (0.01%~0.3%). The zeta potential and particle size can be measured by the PCS method in the room temperature. |
