| 摘 要： | 用表面张力法研究了混合磷酸酯的表面活性，得出各混合体系的临界胶束浓度和临界胶束浓度时的表面张力．结果表明，ＭＡＰＤＡＰ为７０３０时混合体系表面活性最优；ＡＰ、ＰＥ含量低于３％时有利于混合体系表面活性的提高；ｐＨ值在５．５～８．５范围内，对体系的表面活性影响较小

| Abstract: | The surface activity of mixed phosphates was studied by the measurement of surface tension. The critital micelle concentration (cmc) and surface tension of cme of the mixed systems were determined . The results indicate , (1) the surface activity shows a maximum when the ratio between MAP and DAP is 70 : 30 in the mixture ; (2) the surface activity is improved in the presence of AP and PE when the quantity less than 3% ; (3) the effect of pH in media on the surface activity is slight over the rang from 5.5 to 8.5. |
