Investigation of H{sub 2}O{sub 2} catalysis with iron oxide for removal of synthetic organic compounds
- Drexel Univ., Philadelphia, PA (United States)
Hydrogen peroxide is not a strong oxidant for the majority of the organic water and soil contaminants, except for a few easily oxidizable compounds. The objective of this study is to investigate the feasibility of using hydrogen peroxide and iron oxide particles as a chemical oxidant for removal of organic pollutants from waters. In order to establish this objective, an organic compound was oxidized in a laboratory size reactor by hydrogen peroxide in the presence of iron oxide particles. The effect of several parameters on the oxidation efficiency of the compound was investigated. These parameters included the dosages of hydrogen peroxide and iron oxide, stirring speed, and the pH and bicarbonate ion concentrations in the solution. The experiments were conducted in a completely mixed slurry reactor operated in batch mode. Goethite ({alpha}-FeOOH) was selected as the catalysts in this study since it is a common mineral in nature and also has a low solubility in water (Ksp=10{sup {minus}39}). The organic compound selected in this research was n-butylchloride (BuCl). BuCl serves as an OH{sup {sm_bullet}}-probe due to its non-reactivity with hydrogen peroxide but high reactivity with OH{sup {sm_bullet}}.
