Abstract This research seeks to build the fundamental understanding of micelle formation and mobility in supercritical CO2 necessary to develop an innovative phase-transfer extraction system for selectively removing metals (actinides) from contaminated surfaces. We will extract metal ions into supercritical CO2 (scCO2) using CO2 soluble extractants. The surfactants consist of perfluoroether and perfluoroalkyl backbones with phosphate head groups. Experimentation will focus on two main issues: understanding the solubilization mechanism of metals into supercritical CO2 with regards to micelle formation, and studying the interactions between the extractants and surfaces.
