　　内容简介：
　　Membrane processes that use ion-exchange membranes and electric potential difference as the driving forcefor ionic species are called electromembrane processes. The following electromembrane processes can be distinguished:（1）electrodialysis； （2）electro-electrodialysis, (3)membrane electrolysis. In other techniques where ion-exchange membranes are used (such as diffusion or Donnan dialysis) the driving force  is not external electric potential difference but a concentration difference.

　　Electromembrane processes are based on the selectivity of ion-exchange membranes. These membranes contain electrically charged groups fixed to the polymer matrix and allow permeation of ions of opposite sign through the membrane under the influence of an electric field. There are cation- and anion-exchange membranes depending on the sign of the permeating ions. Progress in electromembrane processes was closely connected with developing modern ion-exchange membranes in the early 1950s. The membranes fulfilled bbin电子 and bbin电子 the basic requirements important in electromembrane processes: today they are highly permselective, physically strong and have low electrical resistance. Electromembrane processes have found numerous practical applications and many of these are directly related to environment protection. The following area of application can be listed as the most important in that field: (1)removal of harmful chemicals from effluents or waste gases,(2) recovery and reuse of valuable compounds from wastes; (3) closing the loops in technology;(4) developing new production methods, that require lower energy consumption. Lower energy consumption causes a reduction in environmental pollution by mines, power stations etc.
