Abstract
A method for the determination of pyridine, aniline and o-, m- and p-t oluidine in stack gases is described. These compounds are absorbed in Chromosorb G doped with 4% of orthophosphoric acid. Desorption is carr ied out after alkalization with either benzene or diethyl ether. Recov eries surpass 90%. By sampling 101 of flue gases a determination limit of about 1 mg m(-3) for the individual compound can be achieved. This determination limit decreases as the volume of aspired gas is enhance d.
