Cardiff Research Highlighted in ISIS Annual Review

14 December 2011

Collaborative research from Drs Ian Fallis, Simon Pope, Peter Griffiths and Alison Paul has been highlighted in the ISIS annual review document. ISIS is a muon and neutron source facility based at the Rutherford Appleton Laboratory.

"Nuclear power has played an important role in Britain’s history, and with plans to build 10 new facilities, it is set to play an equally important role in its future. There is a need to develop rapid, selective methods for the detection and speciation of transuranic radioisotopes (e.g. Np, Pu, Am, Cm) in solution, as these elements represent hazardous by-products of the nuclear power industry. In collaboration with Magnox Ltd we are developing microemulsion systems to speciate these radionuclides in liquid wastes, to determine not only the element type and concentration, but also its oxidation state. In essence, a range of water soluble complexing agents have been synthesised that display selectivity towards the radionuclides of interest. The binding of these agents to a radionuclide cation causes them to separate out within the microemulsion. The properties of the cations can then be studied. Small angle neutron scattering (SANS) is being used to probe the separation within the microemulsion system and to discover unique complexing agent – metal cation combinations."
