Description

A preconcentration neutron activation analysis method has been developed for determination of 14 rare earth elements in soil, sediment and some rock samples. The method involves sample melt together with Na2O2, coprecipitation and ion exchange. Unlike usual INAA, this method can greatly improve the sensitivity for the REE other than Er, Pr, Tm, Nd and Ho. The absolute detection limit depends on specific elements, the lowest is 8.4 ng for Eu and the highest 3.92 μg for Pr
