PRECONCENTRATION BY ABSORPTION OF ACTIVATED CHARCOAL AND NEUTRON ACTIVATION ANALYSIS OF TRACE ELEMENTS IN SEAWATER
Abstract:
The optimized conditions are investigated for preconcentration of trace elements contained in seawater by activated charcoal absorption. By apparatus neutron activation analysis under the optimized conditions, we have successfully determined the concentrations of 21 trace elements contained in the seawater of Bohai Bay and 26 trace elements in suspensions. The sensitivity and degree of accuracy of the method are reviewed.
