摘要：

Procedures and theory are presented to determine complexing capacities for nickel in seawater using cathodic stripping voltammetry of complexes with dimethylglyoxime (DMG). Values for beta (Ni(DMG)//2 are determined for seawater of several salinities by ligand competition with EDTA. Preliminary measurements on samples from various locations reveal the presence of low concentrations (2-4 nm) of strong complexing ligands with values for the conditional stability constant, log K prime (NiL), between 17. 3 and 18. 7.
