Abstract

A preconcentration procedure is reported for rare earth elements suitable for concentration levels generally found in rocks. This method is of geochemical interest because the abundance of rare earth elements gives important clues to the origin of rock formations.

The procedure is based on an anion-exchange separation step followed by a precipitation of rare-earth elements chelates onto a membrane filter. For the investigation of recovery a combined radionuclide tracer and X-ray sensitivity method was used. Detection limits in the sub-μg/g-range are reported.
