Trace metals, like iron, copper, zinc and cobalt, in seawater are essential for phytoplankton growth and limit the primary production in some oceanic regions. It is crucial to reveal not only distributions of the metals but also their chemical speciation in seawater because their availability to phytoplankton depends on their speciation. At present, it is well known that more than 99% of iron and copper are complexed with organic ligands in seawater, which was revealed mainly by using voltammetry. In this review, we introduce the electroanalytical methods of organic ligands for trace metals in seawater. Moreover, we indicate the voltammetric methods to determine nanomolar levels of specific organic ligands for trace metals, such as humic substances and thiols, in seawater.
