Solid phase extraction with chelating adsorbents is useful for the preconcentration of trace metals in seawater. We have examined a number of chelating adsorbents and developed simultaneous determination methods for trace metals in seawater on the basis of preconcentration by solid phase extraction and determination by ICP-MS. Here we review the results on the determination of trace bioactive metals(Fe, Co, Ni, Cu, Zn, Cd and Pb)using fluoride-containing metal alkoxide glass immobilized 8-hydroxyquinoline(MAF-8HQ)and the determination of the second and third transition series metals(Zr, Hf, Nb, Ta, Mo and W)using vinyl polymer resin immobilized 8-hydroxyquinoline(TSK-8HQ).
