A test method for the measurement of arylamines in stationary source emissions

摘要

Title III of the lean Air Act Amendments of 1990 lists eighteen arylamines as hazardous air pollutants to be regulated. The eighteen arylamines range from semivolatile to almost nonvolatile, from almost water-insoluble to hygroscopic, from thermally quite stable to unstable, and from fairly toxic to confirmed human carcinogens. This paper presents a report on progress in the development of a method to measure this quite disparate group of compounds in stationary source emissions. The proposed method involves collection in an acidic aqueous solution, sorption of collected arylamines on a cation exchange resin desorption of arylamines form the resin with a small volume of a basic solution, and separation and measurement by high pressure liquid chromatography with photodiode array (HPLC-PDA) detection.
