A test method for the measurement of arylamines in stationary source emissions
- Research Triangle Institute, Research Triangle Park, NC (United States); and others
Title III of the Clean 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 from 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. Evaluation of cation exchange resins and resin elution solvents and the analytical portions of the method are being conducted using a subset of eight arylamines: aniline, chloramben, 2,4-diaminotoluene, N,N-dimethylaniline, 3,3`-dimethylbenzidine, quinoline, o-toluidine, and trifluralin. Sorption on a solid-phase extraction resin (LC-SCX, Supelco) followed by elution off the resin with a 2.2 normal solution of ammonia in a 50:35:15 mixture of 1-butanol, 1-propanol, and water gave the best recoveries of the test compounds (except chloramben, which contains a carboxylic acid group and does not elute) from the acidified collection solution. The compounds were separated on an Alltech Alltima C18 5{mu}m, 150 {times} 4.6 mm HPLC column using solvent programming with acetonitrile and either water or an acetate/acetic acid pH 7 buffer. 1 fig., 3 tabs.
