NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 5th Quarterly Report
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.

NASF continues discussions with US EPA on the agency’s plans for a nationwide survey of the metal finishing industry on its use of PFAS. NASF plans to review the draft survey and provide feedback to the agency prior to its distribution. Surveys will likely go to a wide range of job shop and captive operations and are scheduled to be sent out in the fall.
