According to oceanographic research, trace metals are essential in life of marine phytoplankton, since many trace metals are micronutrients that are essential for biological processes. However, due to extremely low concentrations of trace metals in seawater, it is difficult to measure their concentrations; therefore, specific analysis methods must be performed in order to determine the concentrations of trace metals. One of the techniques, which is required prior to extraction process, is UV-oxidation in which strong organic ligands that chelate trace metals, such as copper (Cu) and cobalt (Co), are destroyed.
