| 摘 要： | 对比了不同十二烷基苯磺酸钠（LAS）浓度和水的硬度对泡沫稳定性的影响，当水的硬度为0时，稳定性在其临界胶束浓度（cmc)达到最高值，超过cmc值，稳定性随LAS浓度增大而降低；当水的硬度不为0，Ca^2 浓度达到最大值时，泡沫高度与Ca^2 的浓度没有关系；出现Ca(LAS)2沉淀后，泡沫高度随Ca^2 浓度的增加而降低。

| Abstract: | The effect of concentration of LAS and hardness of water on stability of LAS foaming are reviewed through the test .When the hardness of water is 0,the stability of foaming reaches its highest cmc value.When the highest cmc value is exceeded, the stability of foaming gets lower as the concentration of LAS increasing. When the hardness of water isn't 0 and the concentration of Ca 2+ reaches the highest value,no relationship exists between the foaming height and the concentration of Ca 2+,after the appearance of Ca(LAS) 2 precipitation,the foaming height is increasing while Ca 2+ concentration decreasing. |
