Description:
The goal of this article was to summarize the recent advances in ion exchange technology for the metal finishing industry. Even though the ion exchange technology is mature and is widely employed in the industry, new applications, approaches and ion exchange materials are emergin at a rapid pace. Much of the information was abstracted from presentations made at "The Trends in Metal Adsorption Workshop" co-sponsored by the U.s. EPA, AIChE, the Council for Chemical Research and the U.S. DOE. Other information was obtained from reviews of Environmental Protection Agency (EPA) sponsored pollution prevention projects, panel discussions and workshops, user surveys and the author's discussions with practitioners in the industry. The objectives of this article in the context of ion echange applications in the metal finishing industry, were: (1) to review advances and applications of ion exchange; (2) to present an overview of commercially available ion exchange technology; and (3) to highlight areas for further research. Many of the technologies discussed achieved improved performance through improved support matrices or through the combination of technologies such as membranes or electric fields with ion exchange.
