Liquid membranes nickel recovery

As a result, liquid-membrane processes have received a great deal of attention for the potential recovery of copper,uranium,1 11 and nickel.10,35,16... 

This review covers recent advances in the theory for emulsion liquid membranes (ELMs) briefly and in ELM applications in more detail. In the theory, the state-of-the-art models for two types of facilitation for ELMs are discussed. In the applications, significant advances have been made recently. Commercial applications include the removal of zinc, phenol, and cyanide fi om wastewaters and in well control fluid. Potential applications include wastewater treatment, biochemical processing, rare earth metal extraction, radioactive material removal, and nickel recovery. The ELM systems for these applications are described.

The recovery of metal ions from rinse solutions is important in electroplating. It has been shown in [291] that nickel ions can be recovered using a liquid surfactant membrane (LSM) obtained on the basis of di(2-ethylhexyl) phosphoric acid. The LMS permeation by nickel ions (external phase) is affected by the membrane viscosity which depends on the surfactant concentration.
