Summary
An ICP-AES method for the determination of 12 rare earth elements and Y is described. Following a Na2O2-sinter dissolution of silicate materials the REE and Y were separated and concentrated using ion-exchange chromatography. The dissolution and separation procedures are described in detail. Numerous tests show good recovery of the REE. Spectral interferences were quantified and discussed. The precision is better than 5% (r.s.d.) for all measured REE, except Pr. The accuracy was tested by analyzing more than 30 international reference samples, the results are in good agreement with published data. In this paper we present our latest data from 6 new reference samples.
