Abstrakt

A simple HPLC method has been developed for the separation and determination of trace level 2-naphthylamine in waste gas. Sample collection was performed directly in a sorption solution containg 0.1 mol.l-1 hydrochloric acid. The separation was achieved on a 150 x 3.3 mm column filled with Separon SGX C18, dp= 5 m. To enhance the selectivity of the method two detectors, diode array (DAD) and electrochemical (ED) in a line system were used. The method permits the measurement of naphtylamine in samples with detection limit 50 ng in 1 ml of the sorption solution for DAD and 10 ng in 1 ml of the sorption solution for ED. The limit of determination depends on the volume of sampling of waste gas.
