Synthesis and application of iron sulfide−based materials to activate persulfates for wastewater remediation: a review

Rapid industrial development has led to excessive levels of various contaminants in natural water, which poses a challenge the innovation environmental remediation technology. In recent years, iron sulfide and its modified materials have attracted extensive attention due their high activity advanced oxidation processes widespread existence anoxic environment. This paper reviewed latest advances synthesis methods for FeS. addition, application persulfate activation by (FeS, FeS x , S−ZVI, FeS@Carbon MFe S y ) is also reviewed, enhancement this system photo irradiation, ultrasound, microwave been concluded. Additionally, interaction mechanism with was reviewed. Based on above contents, we concluded that long−term stability sulfide, toxicity organisms treated combination FeS/PS other assisted technologies should be focused future.
