Distribution coefficients, Kd, between particulate and dissolved phases for the metals in the non UV-irradiation estuarine seawater including dissolved organic matter, were lower than those in the UV-irradiated estuarine seawater. When fulvic acid was added to the mixture of UV-irradiated estuarine water and riverine suspended particulate matter, a decrease in Kds was observed with increasing concentrations of fulvic acid. This indicated that the complexation of the metals with dissolved organic ligands was likely to be one of the important factors decreasing the Kds., 11th International Conference on the Biogeochemistry of Trace Elements}, title = {Influence of Dissolved Organic Matter on the Partitioning of Cobalt and Copper between Particles and Estuarine Seawater}, year = {2011} }
