Abstract
A process for maintaining a charging medium in a microporous molded article for carrying out material transfer processes is described. A charging medium is supplied or presented to the molded article while the material transfer processes are being carried out. This supply takes place on a part of the surface of the molded article which does not participate in the material transfer process. The molded articles are preferably membranes. The process compensates for a loss of medium in the pores of the molded article without requiring the material transfer process to be interrupted. An apparatus suitable for carrying out the process is also described. The process may advantageously be used inter alia for controlled release or slow release processes and processes for facilitated or coupled transport of metal ions.
