Removal of trace levels of 2-acetylaminofluorene (2-AAF) from wastewater.
An adsorption system is described for the removal of part per billion levels of the chemical carcinogen, 2-acetylaminofluorene (2-AAF), from industrial wastewater. The system consists primarily of filters and activated carbon and non-ionic polymeric adsorbents arranged in tandem. It is highly efficient, operates at low cost, and requires minimal attention. The chemical monitoring of the raw and/or cleaned-up wastewater is based on a highly sensitive and specific spectrophotofluorometric method that allows acceptance or rejection of samples at the 0.2 part per billion level. The system is presented as a model for evaluating the removal of traces of organic chemicals from wastewater prior to recycling or discharging it into the environment. Results of laboratory evaluations of several other approaches to the purification of 2-AAF-containing wastewater are also presented.
