| 内容記述 | To investigate the function of dissolved organic matter in the partitioning of cobalt and copper between particulate (>0.2um) and dissolved (<0.2 um) phases, mixing experiments have been carried out by introducing riverine suspended particulate matter into ultra violet (UV)-irradiated estuarine seawater and non UV-irradiated estuarine seawater, collected from northern Sagami Bay, Japan. 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. | |||||
