Abstract: |
|
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. |
