摘　　要：当前国民经济的突飞猛进备受世人瞩目,但在工业生产过程中产生的汞、铬、铜、铅、锌、铀、镍、镉等废液,释放到环境中将会导致水体污染和生态破坏.因此,有毒金属废液的治理迫在眉睫.支撑液膜作为分离领域回收金属离子的一项技术,本文对其构成及分离原理进行了概述,分析了导致支撑液膜不稳定的原因,并基于膜稳定性对衍生出的支撑液膜的类型进行论述.此外,概述了不同类型的支撑液膜技术在金属离子分离回收领域的应用,最后对支撑液膜的工业化应用前景进行了展望.Along with the development of national economy and modern industry, the discharge of effluent such as waste liquid of mercury, chromium, copper, lead, zinc, uranium, nickel and cadmium has become the main source of aquatic ecosystem contamination and ecological destruction. Thus, the treatment of the metal wastewater is imperative. Supported liquid membrane is a promising technology on the reuse of metal ions in separation fields. The separation mechanism of liquid membrane have been summarized and the reasons why operation instability of liquid membrane have been analyzed. Besides, the derivative technologies related to stability have been discussed. In addition, the application of supported liquid membrane technologies on separation and recovery of metal ions have been summarized, and its industrial application prospect has been forecasted.
