A method for removing Na and Sc from activated rocks is described in the deter-mination of REE by neutron activation analysis. Absorbing experiments were carried out on improved HAP
using
24
Na
46
Sc
59
Fe
141
Ce and
155
Eu as indicators. Almost 100%
24
Na and more than 95%
46
Sc were removed in an improved HAP column.
Finally
the determination of REE in OPH 163 rocks by the combinatory neutron activation analysis using present method has been carried out. Experimental data indicated that more than three elements (Pr
Nd and Ho) have been determined by this method
as
compared with non-destructive neutron activation anlysis and the proposed method was sensitive and feasible.
