✦ Synopsis

Dissolved copper can he rapldly detemuned m sea water by usmg a moddkation of a chemdummescence method The determmation 18 based on the formation of a complex between copper and l,lO-phenanthrolme and the subsequent enusslon of bght dunng the oxldatron of the complex by hydrogen peronde A flow-mJe&on mamfold was constructed which prondes for the separation of copper f'rom the sea water matnx mth a column of Immobked 8-hydroxyqumolme The column eluant was mjected into a tamer stream, mixed with the reagents and debvered to a flow cell where ermtted bght was detected and used to quantify the amount of copper us the sample The technique IS noteworthy for its low detechon bnut ( < 0 4 nM), the rapidity of sample processmg (approxnnately 8 mm sample-'), the small sample volumes requued (approxunately 4 ml), and the mmlmal precautions necessary for the prevention of sample contammation durmg shipboard processmg mrds Flow Iqlection, Chemdummescence, Copper, Sea water
