摘要：

The adsorption of metal elements on hydrated ferric oxide, clay minerals, and marine sediments from artificial seawater is studied using radioactive multirracers produced by MEN Ring Cyclotron. The distribution coefficients (Kd) of Co, Ga, Rb, Sr, Y. Zr, Nb, Mo, Ru, Rh, Pd, Ag, In. Sri, Eu, Gd, Tb, Tm, Yb. Lu, Hf, Re and Hg were determined. The order of Kd for each element is summarized as follows: hydrated ferric oxide > deep-sea sediment > montmorillonitea nearshore sediment kaolinite. It is inferred from the observation that hydrated ferric oxide plays an important role in removing metal elements from seawater.
