Novel environmentally friendly catalytic oxidation approaches on elemental mercury removal from carbon steel surface

To date, technology for the removal of elementary mercury adsorbed on carbon steel surfaces with very minimum iron (Fe) leaching is apparently missing. In this study, the oxidation reaction of mono-peroxyacetic acid (PAA) was used in the presence of Ru/Mn/Al2O3 catalyst to enhance the treatment remo...
