Separation and Extraction of Plutonium in Mixed Waste

Abstract

This experiment established the effective lifetime of an activated carbon fiber felt adsorption column in which the ends are covered with an impermeable plastic film is able to effectively remove Krytox 157 surfactant from PF-5070. It was shown that the column effectively removed 90% of the Krytox 157 from five-adsorber volumes (40 L) of 0.4% Krytox 157FS solution, pumped at one adsorber volume every hour. Without these end sheets of polyethylene, the effective lifetime is reduced to approximately two adsorber volumes (16 L).
