The electrolytical dechlorination is one of the most often used methods, but its electrochemical conditions for cleaning bronze objects have not yet been described exactly. There is need to define these conditions and device arrangement in order the effectiveness of chloride ions elimination from the metal object could be determined. In the project following tasks will be solved: electrolytical dechlorination of the iron archeological objects with the successive treatment by the sulfate method, electrolytical dechlorination of the bronze archeological objects, evaluation of the cleaning level of the object surface corrosion products before and after treatment, characterization of the environment in selected expositions and depositories. The results of this project will be published in special journals and presented on the conference of museum conservators-restorers. The methodological guides for the electrochemical treatment of bronze objects from the museum collections and for the depository climat.
