Dual-pathway persulfate activation by mackinawite (FeS) for contaminant degradation: Overlooked role of Fe(IV) species and QSAR model

Key Points

• Contaminant degradation is enhanced by the presence of fe(IV) species, unlocking a new pathway for treatment.
• The dual-pathway mechanism for persulfate activation shows significant effectiveness, particularly in the degradation process.
• Analysis across various models supports the findings, establishing a connection between fe(IV) species and contaminant removal.
• This approach highlights the importance of iron-based strategies in environmental remediation; further research is encouraged.
