GAS CHROMATOGRAPHIC METHOD FOR DETERMINATION OF TRACE AROMATIC AMINES IN WATER

Gas chromatographic methods for determination of trace aromatic amines in water was reported in this paper. Special methods for extraction and separation of aromatic amines form water samples were described. Cation exchange resin can be used to extract and separate aromatic amines from water with recovery rate of about 85%. In the experiment, aromatic amines were dervvatized with fluorine containing compound, and determined by GC with recovery rates in the range of 83.9 to 94.1%. Becarse of higher resolution of capillery column and high sensitivity of electron capture detector to fluorine containing compound, the detection limits of the method were 20-50 ppt depending upon individual aromatic amine.
