Abstract
The invention concerns the use of carboxylic acids or their salts as the basic corrosion-protection component of agents for the treatment of metal surfaces, as well as a method of separating such agents from an aqueous medium after use in accordance with specified procedures, recovering the carboxylic acids and, optionally, recycling them in a suitable agent.
