Updating Hexavalent Chromium Detection Capabilities
An industry safety expert suggests testing methods to detect hexavalent chromium needs to adapt to ever changing industrial environments to provide shorter time-sample results.
An industry safety expert suggests testing methods to detect hexavalent chromium needs to adapt to ever changing industrial environments to provide shorter time-sample results, such as 5- or 10-minute increments and with accuracy near laboratory testing.
Alex Mazzotta, a mechanical engineer at Figure Engineering based in Lorton, Virginia, writes in an article that appears in the September 2019 issue of Occupational Health and Safety that such capability will significantly enhance visibility on exposure, but he says what’s even more impactful is the ability to determine potentially unknown sources of dust or fumes that expose unprotected personnel.
Mazzotta writes, “at the United States Air Force depot at Hill Air Force Base, there was an issue just like this. Within a large building where abrasive blasting takes place in a large walk-in blast booth, OSHA found Cr(VI) exposure to be far in excess of mandated PELs. This shed light on a series of unidentified sources in the building that were generating Cr(VI) fumes and dust.”

NASF/AESF Foundation Research Project #120: Electrochemical Destruction of Perfluorooctanesulfonate in Electroplating Wastewaters – January – December 2023
This NASF-AESF Foundation research project report covers quarterly reporting for the year 2023 at the University of Illinois at Chicago. The objective of this work is to utilize a cost-effective reactive electrochemical membrane (REM) for the removal of PFAS from synthetic electroplating wastewater. Discussed here are the oxidation of PFOA with three different catalysts, development of a method for detecting PFAS, as well as work on 6:2-fluorotelomersulfonic acid (6:2 FTS) and electrodeposited bismuth/tin oxide catalysts.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 9th Quarterly Report
The NASF-AESF Foundation Research Board selected a project addressing the problem of PFAS and related chemicals in plating wastewater streams. This report covers the ninth quarter of work (January-March 2023). In this report, we describe our work on evaluating the performance of PFAS degradation by electrooxidation using surface fluorinated Ti4O7 anodes in batch mode.

NASF/AESF Foundation Research Project #122: Electrochemical Approaches to Treatment of PFAS in Plating Wastewater - 12th Quarterly Report
This NASF-AESF Foundation research project report covers the 12th quarter of project work (October – December 2023) at the University of Georgia. In our previous report, we described our work on performance and effect of surface fluorinated Ti4O7 anodes on PFAS degradation in reactive electrochemical membrane (REM) mode. This quarter, our experiments involved utilizing porous Ti4O7 plates serving both as anodes and membranes. Tests compared pristine and F-18.6 Ti4O7 anodes at current densities of 10 mA/cm2 and 40 mA/cm2. This 12th quarterly report discusses the mechanisms of the effects on EO performance by anode surface fluorination.
