Application of Ultrasonic Wave to Separation He Mei, Xia Zhining*, Guo Baoyuan, Wang Li# Abstract Ultrasound can enhance the separation
efficiency, shorten the work time and simplify the work process. This paper exhibits the
application of ultrasonic wave in chemical and biochemical separation fields, including
abstraction, membrane separation, electrochemical separation, floatation, extraction,
precipitation and two-aqueous phase extraction, crystallization and so on. The
characteristics of the combination between ultrasound and separation, and the further
application of ultrasonic separation, are discussed.
分离技术中超声波的应用现状 何 梅 夏之宁* 郭宝元 王 力# 摘要
在分离技术中,利用超声波的空化作用、热作用、机械作用、以及这些作用的附加效应的结合发挥,可提高分离效率、缩短时间、简化操作过程。本文综述了超声波在化工分离如膜分离、电渗析分离、浮选、沉淀、浸取等,生化分离如细胞破碎提取、双水相萃取、结晶等各种分离方法中作为辅助手段的应用和研究现状,并对超声波与分离方法结合的特点及发展前景进行了探讨。 何梅
