Abstract

A stopped-flow rapid mixing device interfaced to a high performanceminiature fibre optic CCD NIR detector permits the study of fast redox kineticsof actinide reactions at minimal cost. The use of fibre optics enables thestopped-flow device to be readily used in a glove-box. The system has beenevaluated at 980 nm by observing the in-growth of Np(V) from a fast reductionreaction of Np(VI), and has been shown to perform well in this spectral region.
