Article Synopsis
- The study analyzed how various cathode materials (platinum, copper, and iron) affect the degradation of iohexol in a cathode/Fe/PMS process, highlighting that optimal conditions vary by cathode type.
- At higher current inputs (2.0 mA/cm), the performance of all cathodes was similar, but at lower current inputs, the order of effectiveness was Fe-cathode > Cu-cathode > Pt-cathode due to varying levels of corrosion.
- The research also found that the degradation mechanisms differed by cathode: sulfate radicals (SO) were more significant for the Cu-cathode, while hydroxyl radicals (OH) dominated for the Pt and Fe cathodes, leading to distinct
Copper was used as a non-inert cathode material in a Cathode/Fe/peroxymonosulfate(PMS) system, and the performance of this novel Cu-cathode/Fe/PMS system was tested with a typical iodinated X-ray contrast media (iohexol) as target organics. The reaction mechanisms and the iohexol degradation pathways were investigated. The operational conditions of Cu-cathode/Fe/PMS process on iohexol degradation were optimized to be 1.
