| A new effective water treatment method with iron electrode electrolysis has been developed. The aim of this method is to purify wastewater containing harmful organic compounds, such as landfill leachate. The method does not need any chemical additives. Organic compounds in wastewater are adsorbed by colloidal particles of iron species formed in an iron electrode electrolysis process, and then the colloids adsorbing organic compounds are removed in a strong magnetic separation process. To remove organic compounds effectively, we have researched the relations between growing rate of the colloid sizes adsorbing four organic compounds and their chemical structures; bisphenol A(4,4'-isopropylidenediphenol) and diethylphthalate, which are suspected to be endocrine disruptors, and m-,p-cresols. The growing rate for bisphenol A was the fastest among them. This result shows that bisphenol A is most strongly coupling with the colloids of iron species and is scavenged effectively. |
