Determination of aromatic amines in surface waters and comparison of their behavior in HPLC and on sediment columns.
An analytical method based on solid-phase extraction (SPE) with a polymeric material, HPLC separation on a modified C18 material, and diode-array detection is presented for the determination of aromatic amines in the ng L(-1)-concentration range. These potentially toxic compounds in polluted water samples can be sampled by using SPE with an amino phase to clean the eluate. Column experiments were performed to characterize the transport behavior of aromatic amines in an aquifer sediment. For nineteen aromatic amines, linear correlations were found between the adsorption coefficient, Kd, estimated from column experiments, and capacity factors, k', measured by isocratic reversed-phase HPLC (RPHPLC).
