摘要：

Procedures based on the application of immobilized quinolin-8-ol silica gel and stripping voltammetry were developed for the determination of copper, lead, cadmium, bismuth, indium and zinc in sea water. As two concentration steps are involved, better sensitivity and lower detection limits could be achieved with the application of smaller sample volumes. The feasibility and reliability of the developed procedures were confirmed by the analysis of a near-shore sea-water sample and CASS-2 reference sea water.
