摘要：
Chemical polishing based on phosphoric acid mixtures is used for producing a bright finish on aluminium prior to anodizing. As the solution ages, replacement in part or full with new polishing solution is generally necessary. The paper outlines methods employing ion exchange and evaporative techniques which achieve economical advantages.
