The adsorption of metal elements on hydrated ferric oxide, clay minerals, and marine sediments from artificial seawater is studied using radioactive multitracers produced by RIKEN Ring Cyclotron. The distribution coefficents (Kd) of Co,Ga,Rb,Sr,Y,Zr,Nb,Mo,Ru,Rh,Pd,Ag,In,Sn,Eu,Gd,Tb,Tm,Yb,Lu,Hf,Re and Hg were determined
