The advanced oxidation process based on persulfate has a broad application prospect in the remediation of organic pollutants. As an effective, low-cost and environmentally friendly material, nano-zero-valent iron (nZVI) can effectively activate (nZVI/PS) to generate strongly oxidizing sulfate radical for removing pollutants environment. In this review, we first clarify activation pathway nZVI a...

In recent years, advanced oxidation process (AOPs) based on sulfate radical (SO4??) and singlet oxygen (1O2) has attracted a lot of attention because its characteristics rapid reaction, efficient treatment, safety stability, easy operation. SO4?? 1O2 mainly comes from the activation reaction peroxymonosulfate (PMS) or persulfate (PS), which represent reactions involving radicals non-radicals, r...
