Data from H. Park and Colleagues Advance Knowledge in Environmental Pollution (Iron Oxide Nanoparticle-Impregnated Alumina for Catalytic Ozonation of para-Chlorobenzoic Acid in Aqueous Solution)

By a News Reporter-Staff News Editor at Ecology, Environment & Conservation -- Data detailed on Environmental Pollution have been presented. According to news reporting from Taejon, South Korea, by VerticalNews journalists, research stated, "A granular media synthesized using iron oxide nanoparticle-coated alumina (IONA) has been demonstrated as an effective solid catalyst in the heterogeneous catalytic ozonation of para-chlorobenzoic acid (pCBA). TEM analysis showed that iron oxide nano-particles with an average size of 5-20 nm were well-coated onto an alumina surface."

The news correspondents obtained a quote from the research, "It was determined that the iron oxide nanoparticle coating increased the specific surface area by 54 times and the functional group density by 1.5 times. During catalytic ozonation at acidic pH levels, it was clearly observed that IONA increased the degradation of pCBA (98 %) through effective hydroxyl radical formation compared to bare alumina (9 %) under continuous ozonation processes. In comparing the R-ct value, which represents the ratio of ozone exposure to hydroxyl radical exposure, the R-ct of IONA was approximately four times higher than for bare alumina."

According to the news reporters, the research concluded: "In addition, IONA showed good stability for catalytic ozonation of pCBA in the reusability tests."
