Wet digestion method had been used in river deposit of BZ profile. At the same time, Mn, Cu, Ba, Ni, Pb, Zn, Rb, V, Sr and Zr in river deposit were determined by ICP-OES. The results show that the relative standard deviations are all below 0.39%, while the recovery of standard addition is 94.3%~117.1%. The method is proved to have good precision and accuracy, and to be simple and rapid. And the measured data provide basis for paleoflood study in this area.
