Nanoscale zero valent iron-activated persulfate coupled with Fenton oxidation process for typical pharmaceuticals and personal care products degradation

In this study, a two-staged nanoscale zero valent iron-activated persulfate coupled with Fenton (nZVI-PS-Fenton) oxidation process is applied to remove typical pharmaceuticals and personal care products (PPCPs) from water. Due to the partial substitution of PS by cheaper H2O2, the main advantage of the combined treatment is to reduce the cost of oxidation reagent and reduce sulfate release in water. Experiment results indicated that...
