Chromium Removal from PVC Filters

Chromium metals and hexavalent chromium are known health hazards monitored in workplace environments. Occupational health professionals use polyvinyl chloride (PVC) in disc filters to monitor total chromium present in a workplace. If chromium background is present in the filters, the interpretation of the results can be problematic. Current analytical analysis methods can't discern environmentally harvested chromium materials from chromium that is present as a result of manufacturing byproducts in the filters. A need exists for a non-destructive method of removing the background concentration of chromium metals and hexavalent chromium that is present in the PVC filters.
