Organic water pollution is calling for advanced remediation methods such as the Fenton process, yet actual procedures involve transition metals at acidic pH, and generate only one oxidant, the hydroxyl radical. Here we used a solution of magnesium ions, bicarbonate ions, and hydrogen peroxide at pH 7.4 to generate reactive oxygen species for degrading dimethyl sulfoxide and acetamidophenol, as models of water pollutants. The performance...
