The NASF-AESF Foundation Research Board has selected a project on addressing the problem of PFAS and related chemicals in plating wastewater streams, studying PFAS destruction via electrooxidation and electrocoagulation. Our last report described the results from experiments of EO with a Magnéli phase Ti4O7 anode on the degradation of eight perfluoroalkyl acids (PFAAs). In this seven quarter report, we describe work to further explore how the degradation of different PFAAs are related to their molecular structures.
The NASF-AESF Foundation Research Board has selected a project on addressing the problem of PFAS and related chemicals in plating wastewater streams, studying PFAS destruction via electrooxidation and electrocoagulation. This sixth quarter report covers the continued assessment of eight perfluoroalkyl acids PFAAs most commonly found in wastewaters, by electro-oxidation with a Magnéli phase Ti4O7 anode across a range of anodic potentials in solutions, exploring the reaction mechanisms. To summarize, the PFAAs start to exhibit degradation behavior when the anodic potential reaches a level where water oxidation occurs, suggesting that the hydroxyl free radicals generated via water oxidation play a role in PFAA degradation.
On display at SUR/FIN 2021: Moonstone’s environmentally beneficial systems to treat wastewater streams.
Met-Chem to showcase complete wastewater treatment systems, from recovery to chemical treatment.

This paper covers a research grant at the University of Georgia - Griffin on developing electrochemical approaches to remove PFASs present in plating wastewaters, under the direction of Professor Qingguo (Jack) Huang. This fifth quarter report assessed eight PFAAs most commonly found in wastewaters, by electro-oxidation with a Ti4O7 anode across a range of anodic potentials in solutions of different compositions and at varying operating conditions.
Removal of Organic Bound Phosphorous from Wastewater
This eighth quarter report covers work to prepare and characterize surface-fluorinated Ti4O7 anodes to enhance further the PFAS degradation process.
