Abiotic As(III) oxidation by hydrated Fe(III) oxide (HFO) microparticles in a plug flow columnar configuration

Abstract:

Abiotic As(III) oxidation by hydrated Fe(III) oxide (HFO) microparticles in a plug flow columnar configuration was discussed. The plug flow configuration of the system allowed thousands of contacts with Fe(III) sorption sites for each As(III) molecule, thus enhancing As(III) oxidation in accordance with law of mass action effect. It was found that at acidic pH, conversion of As(III) to As(V) was much less pronounced due to unfavorable thermodynamics.
