UV/vis Spectroscopy of Eu(III) and Am(III) Complexes with Small Organic Acids at Variable Temperatures

Müller, M.; Acker, M.; Taut, S.; Bernhard, G.

Thermodynamic data for reactions of trivalent Actinides in the host rock environment are required for analysis of long-term safety of nuclear waste disposals in clay. We analyzed the complexation behaviour of Eu(III) and Am(III) with benzoic acid derivatives, which structures are similar to the natural organic matter.

Keywords: UV/vis spectroscopy; complexation; americium; europium; temperature dependence; thermodynamic data
