摘要
测定了全氟辛酸铵和全氟壬酸铵及其不同比例混合物的0.1 mol/L氯化铵水溶液表面张力曲线。讨论了它们的胶团化作用、吸附作用和降低水表面张力的能力。改进了Ingram-Luckhurst自单一表面活性剂活性张力曲线得到混合溶液表面张力曲线的方法。
The surface tension isotherms of ammonium perfluorooctanoate, ammonium perfluo-rononanoate and their mixed aqueous solutions with ammonium chloride (0. 1 mol/L) have been measured by using drop volume method at 25℃- The micellization, adsorption and surface tension reduction in these systems are discussed. A new method for calculating the whole r-lgC curves of the ideal solutions of the mixtures was developed and good correspondence between the calculated and experimental results was obtained.
