Abstract

Since emulsion liquid membrane (ELM) was found by Li in the late 1960s$^{[1]}$ , a great amount of work has been conducted on the research and application of ELM$^{[2-8]}$ . Generally, during a process of ELM separation, three types of emulsions will be shown in turn. They are primary emulsion, multiple emulsion, namely ELM, and recovered emulsion respectively. Those three types of emulsions inevitably share some common properties, and at the same time, because those three types of emulsions emerge in different stages of ELM separation, some differences will be observed.(omitted)
