摘要： The invention concerns an agent, based on organic compounds obtained from micro-organisms, for removing rust from metal surfaces corroded with iron oxides. Rust is normally removed from metal articles using corrosive baths containing organic and/or inorganic acids which, owing to the concentrations used, must meet certain safety requirements and entail costly disposal procedures once the baths are depleted. Iron-absorbing products obtainable using biological methods are generally active in the neutral pH range, eliminating the salt production and contamination of the effluent associated with the neutralisation process normally required. Rust can be removed using reproducible intra- or extra-cellular products which have a high affinity with iron ions. The proposed agents are produced by culturing appropriate organisms in a suitable medium in such a way that they are stimulated to produce these agents. The articles requiring de-rusting are then treated by being dipped in or painted with the agent. Provision of appropriate supports to immobilise the articles facilitates use of the agents and permits recycling of the agent by suitable treatment.
