Resumo(s)
Electrokinetic desalination is a method where an applied electric DC field is
the driving force for removal of salts. The method is under development for desalination of
brick masonry and stone monuments. In the present paper, the method is suggested for
extraction of salts from tile panels, as well. It is suggested to remove few tiles from the
panel, place electrodes in the holes and desalinate the wall and mortar behind the tiles. It
was shown experimentally, that electrokinetics can be used for desalination of the tiles (96%
Cl removed in less than 6 days). The method might be a conservation method to salt
damaged tile panels.
