| Abstract: | A flow injection preconcentration system was coupled with double Sep-Pak cartridges to extract the complex of copper-8-hydroxyquinoline from the seawater samples. 8-hydroxyquinoline was added previous to the preconcentration. The complex was eluted by methanol and the eluent was delivered by the flow injection system to a flame atomic absorption spectrometer for the online detection. The preconcentration factor for 100 ml seawater sample could be over two orders of magnitude. The detection speed was 10 determinations per hour. The reproducibilily of the preconcen-tration-detection was within the range of 2. 0 to 5. 7%. The seawater samples examined contained copper of 3 to 7 ng/ml. |
