Separation and preconcentration of actinides from concentrated nitric acid by extraction chromatography in microsystems

A new versatile impregnation method was developed in microsystem to functionalized methacrylate polymers. These robust microcolumns could have an application for the separation of actinides in nitric acid as it was demonstrated for the separation of U, Th and Eu in HNO3 5 M For tributylphosphate impregnated monolith.147
