摘　　要：利用泡沫扫描仪研究了不同种类表面活性剂及其复配体系的起泡性、稳泡性和抗盐性.结果表明,在去离子水中有5种表面活性剂的起泡体积大于160 mL,泡沫半衰期超过60 min.无机盐对α-烯烃磺酸钠(AOS)、椰油酰胺丙基二甲基甜菜碱(CAB)和非离子双子表面活性剂(DWS)的泡沫性能影响较小.DWS含量在80%附近,AOS/DWS和CAB/DWS的泡沫稳定性得到明显改善.The foaming ability, foam stability and salt-resistance of different surfactant and its compounded systems are researched by using foam scanner. The results show that five kinds of surfactant have good foam properties in deionized water. The foam properties of non-ionic gemini surfactant （ DWS）, sodium alpha-olefin sulfonate （AOS） and cocoamidopropyl betaine （CAB） are good in salts solution. When the DWS content is about 80%, the foam stability of AOS/DWS and CAB/DWS compounded systems get significant improvement.
