Popis:	A new application of electrolysis for the dechlorination of copper alloys has been developed. Electrolytic treatment with weak polarization in sodium sesquicarbonate permits the extraction of the chlorides and the preservation of the stable alteration products. It is more effective and less time-consuming than chemical methods. The method has been applied successfully to archaeological objects from both marine and land sites.
