Impact/Purpose:
Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals used to modify surfaces properties of fabrics, carpets and furniture, and as fire retardants, present a public health challenge due to the wide range of drinking water contamination.The product is to address PFAS issues in drinking water.
Description:
Per- and polyfluoroalkyl substances (PFAS) are a class of synthetic chemicals used to modify surfaces properties of fabrics, carpets and furniture, and as fire retardants, present a public health challenge due to the wide range of drinking water contamination. Exposure to PFAS, most notably perfluorooctanoic acid (PFOA) causes health risks including thyroid disease, and several cancers. 1,2 PFOA is very stable, persistent in the environment, and hard to be decomposed by traditional technologies due to the strong covalent carbon-fluorine (C-F) bond. Considering the saturated electronic status of C-F atom in PFOA, the reductive conditions are preferred for degradation.2 Herein, we demonstrate an innovative technology for efficient removal of PFOA from the water using photocatalytic reduction approaches. Our protocol uses UV-vis light and scalable, low cost, magnetically retrievable and reusable heterogeneous ZnxCu1-xFe2O4/oxalic acid for the treatment of PFOA. This accessible approach might lead to a new technique in PFASs treatment which will bring the industrial application of water purification at a reduced cost.
