摘要
本文考察了不同分子量的染料，溴百里酚兰和染料废水等在超声作用下，通过醋酸纤维素膜的透水率与透盐率。发现超声在膜分离中有明显的加速传质和去“浓差极化”作用，可以提高膜的分离效率，而作用强弱与膜的性能。
This research has been focused on the affect of ultrasound on the reversed osmosis and permeability of some dyes with different molecular weights(sizes)such as bromothymol blue and a kind of dyewaste water,through cellulose acetate membrane.The ultrasonic actions could increaase mass transport and removed the concentration polarization,which increased somehow separation efficient.The influences from ultrasonics on membrane separation are depend on the applied pressure and the natures of the membrane and the separated species.
