Effective removal of 2,4,6-trichlorophenol by FeSx/talc composite under microwave

Microwave-enhanced degradation is an effective method to remove organic contaminants from aqueous solutions. In this study, we prepared a novel iron sulfide/talc composite. Under microwave irradiation, the hydroxyl and sulfate radicals are rapidly released from the as-prepared FeS x /talc composite (TF), which could remove 106.8 mg/(min·g) of 2,4,6-TCP in 4 min. The maximum chemical oxygen demand (COD) removal was more than 90.1% when the concentration of TF is 1 g/L and the irradiation time of microwave radiation was 5 min, significantly higher than that treated by FeS x particles or talc. It is attributed to the synergetic effect between talc layers and FeS x particles, which greatly enhances the catalytic degradation performance of the composite for organic pollutants . With the advantages of low cost, high physico-chemical stability, and high reusability, this novel FeS x /talc composite could be a potential treating material for rapidly remove organic pollutants from wastewater.
