Abstract:
A non-destructive process for removing chromium from polyvinyl chloride filters is disclosed. The process involves immersing the polyvinyl chloride filters in a concentrated hydrogen peroxide solution at elevated temperatures, followed by rinsing with deionized water. Removing the background concentration of chromium from the filters allows for more accurate measurements of the amount of hexavalent and total chromium present in workplace environments.
