| 摘 要： | 通过试验研究了超声波对脂肪醇聚氧乙烯醚硫酸钠(AES)和聚山梨酯-80(Tween-80)溶液表面张力系数的影响,测量了AES溶液化学需氧量的变化。得到:掺入AES和Tween-80表面活性剂后,水的表面张力系数显著降低了,表面活性剂的浓度越大,其表面张力越小。表面活性剂溶液经超声波处理后:表面张力系数有一定的上升,超声波功率越大、作用时间越长,表面张力系数上升越大;随着超声波作用时间的增加,AES溶液的化学需氧量越来越小,但随作用时间的增加,下降的趋势变慢。

| Abstract: | A study was conducted about the effects of ultrasound on coefficient of surface tension of the sodium alcohol ether sulphate （AES） solution and the Tween-80 solution. The chemical oxygen demand of AES solution was measured. The coefficient of surface tension of water reduced significantly when AES and Tween-80 were introduced. The concentration of surface active agent is higher, the coefficient of surface tension is smaller. The coefficient of surface tension increased with the power and the action time of ultrasound when the solution were treated by ultrasound. The chemical oxygen demand of AES solution is more small with the increase of the action time of ultrasound., but the trend downward slowed down. |
