ABSTRACT- The fate of fluorinated substances in the environment and their routes into the environment are areas of regulatory, industrial and academic interest. Textiles and paper are often incinerated when they are disposed. No information regarding emissions from incineration of textiles or paper treated with fluorotelomer-based products is available. This paper reports the first known studies to investigate the thermal degradation behavior of a fabric treated with a fluorotelomer-based acrylic polymer under laboratory conditions conservatively representing typical municipal incineration conditions of time, temperature, and excess air level. Additional laboratory-scale non-flame thermal degradation studies from 600 to 1000 degrees C for gas-phase residence times of 2.0 seconds were conducted to establish the temperature at which 99.9% destruction was achieved. Carbon mass balance was achieved. The thermal reactor effluent was analyzed by in-line GC/MS to identify degradation products. The details of the experimental procedures and results will be presented.
Key words: environmental fate, incineration, fluorotelomer
