**3. Removal of heavy metal ions with Octolig®**

Remaining sections of this chapter are concerned with research involving the commercially available supported chelating agent called Octolig® because large quantities were available for a very reasonable cost (a wholesale price prior to 2008 was \$40 per kilogram), and a collaboration was established with Robert Alldredge on the basis of mutual interest in the supported chelators, as noted elsewhere [10].

Examples of the removal of heavy metal ions by Octolig® may be found in three areas: patents, company literature, and refereed journals.
