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 FeSx/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 FeSx particles or talc. It is attributed to the synergetic effect between talc layers and FeSx 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 FeSx/talc composite could be a potential treating material for rapidly remove organic pollutants from wastewater.

Automated summary

Microwave-enhanced degradation using the novel FeSx/talc composite is effective in rapidly removing organic pollutants from aqueous solutions. The synergistic effect between talc layers and FeSx particles greatly enhances the catalytic degradation performance, resulting in a COD removal rate of over 90.1%.
