Summary of main observation and conclusion We present a new method for generating europium oxalate compounds by decomposing of N ‐methyl 2‐pyrrolidone in HNO 3 media. The reaction exhibits high selectivity towards Eu 3+ over UO 2 2+ , which suggests that these conditions could be applied to a selective crystallization based separation system for trivalent lanthanides and hexavalent actinides.
