Abstract

A combination of Fenton's reagent with electrochemistry has been demonstrated to be a efficient method for removing a dye (Lissamine Green B) from clays (kaolin, montmorillonite) and soil. The two-step approach described here involved quantitative extraction with hot water, followed by quantitative removal of the Lissamine Green dye by column chromatography using Octolig®. The advantage of this procedure is success without the need for Fenton reagents or electricity. A disadvantage is the process would not work with polycyclic hydrocarbons such as phenanthrene, though the electro-Fenton degradation does.
